Answers

Q1: Option (D)
Q2: 19
Q3: 3
Q4: Option (D)

Solutions

CAT 2017 – Data Interpretation
Data Interpretation - Set - At a management school

Q1)
CAT 2017 – Data Interpretation
As per the options, Dorm 1 needs a moderate repair is possibly true. Dorm 5 does not need more than Rs.4 crore, which is true.
Hence, Dorm 10’s repair not costing more than Rs.4 crore is not necessarily true as it may require Rs.6 crore or Rs.1 crore.
Option (D)

Q2)
CAT 2017 – Data Interpretation
As per the question, number of dorms with repair cost as 3 crores = 3
Since Dorm 1 and 2 already have the repair cost as Rs. 3 crores.
So, out of Dorm 5 and 9, only one can have the repair cost as Rs. 3 crores
Total cost = 3+3+3/4+6+4/3 = 19
Ans : 19

Q3)
CAT 2017 – Data Interpretation
4 of the 10 dorms are women’s dorms which need Rs.20 crore for repairs. As per the question, from 1 to 5 there is only one women’s dorm. This is possible with repairing costs Rs.6, Rs.6, Rs.5 and Rs.3 crore. Among the first 5, dorm 4 should be women’s dorm. Rs.6 cr dorms can only be dorm 7 and dorm 10. Rs.3 crore can be from dorm 1, 3, 5 or 9. But 1, 3 or 5 are not women’s dorm. So it has to be dorm 9.
The repair cost for dorm 9 is Rs.3 crore. So, 3 crore is the right answer.
Answer: 3

Q4)
CAT 2017 – Data Interpretation
4 of the 10 dorms are women’s dorms which need Rs.20 crore for repairs. Also from 1 to 5 there is only one women’s dorm. This is possible with repairing costs Rs.6, Rs.6, Rs.5 and Rs.3 crore. Among the first 5, dorm 4 should be women’s dorm. Rs.6 cr dorms can only be dorm 7 and dorm 10. Rs.3 crore can be from dorm 1, 3, 5 or 9. But 1, 3 or 5 are not women’s dorm. So it has to be dorm 9.
Dorm 10 should be women’s dorm.
Option (D)

Data Interpretation – Set – An old woman had the following assets

DILR – Data Interpretation – Set

The following set contains four questions related to Data Interpretation. Choose the best answer to each question.

CAT 2017 - Afternoon slot - LRDI - Data Interpretation - Set- An old woman had the following assets
An old woman had the following assets:

(a) Rs. 70 lakh in bank deposits
(b) 1 house worth Rs. 50 lakh
(c) 3 flats, each worth Rs. 30 lakh
(d) Certain number of gold coins, each worth Rs. 1 lakh

She wanted to distribute her assets among her three children; Neeta, Seeta and Geeta.

The house, any of the flats or any of the coins were not to be split. That is, the house went entirely to one child; a flat went to one child and similarly, a gold coin went to one child.

Questions

Q1) Among the three, Neeta received the least amount in bank deposits, while Geeta received the highest. The value of the assets was distributed equally among the children, as were the gold coins.

How much did Seeta receive in bank deposits (in lakhs of rupees)?
A) 30
B) 40
C) 20
D) 10

Q2) Among the three, Neeta received the least amount in bank deposits, while Geeta received the highest. The value of the assets was distributed equally among the children, as were the gold coins.

How many flats did Neeta receive?

Q3) The value of the assets distributed among Neeta, Seeta and Geeta was in the ratio of 1:2:3, while the gold coins were distributed among them in the ratio of 2:3:4. One child got all three flats and she did not get the house. One child, other than Geeta, got Rs. 30 lakh in bank deposits.

How many gold coins did the old woman have?
A) 72
B) 90
C) 180
D) 216

Q4) The value of the assets distributed among Neeta, Seeta and Geeta was in the ratio of 1:2:3, while the gold coins were distributed among them in the ratio of 2:3:4. One child got all three flats and she did not get the house. One child, other than Geeta, got Rs. 30 lakh in bank deposits.

How much did Geeta get in bank deposits (in lakhs of rupees)?

Answers

Q1: Option (C)
Q2: 2
Q3: Option (B)
Q4: 20

Solutions

Amount in Bank Deposits = 70 lakhs
Amount for 1 house = 50 lakhs
Amount for 1 flat = 30 lakhs
Amount for 3 flats = 90 lakhs
Number of gold coins = n
Amount in gold coins = n lakhs
Total Amount = 210 + n
House will go to only one person, 1 Flat will go to only one person and 1 Gold coin will go to one person

Q1)
CAT 2017 – Data Interpretation
Assets were divided equally among the three and so were the gold coins.
Gold coins each daughter will receive = n/3
Total Amount with each person = (210 + n)/3
Total Amount with each person – Number of gold coins = 70
One child will get the house (worth Rs. 50 lakhs). Flat can’t be given to this child as it is worth 30 lakhs and limit will be exceeded. So, the child will get 50 lakhs (House) + 20 lakhs (Bank Deposits)
Second child will get 2 Flats (60 lakhs) + 10 lakhs (Bank Deposits)
Third child will get 1 Flat (30 lakhs) + 40 lakhs (Bank Deposits)
Neeta gets the minimum amount of Bank Deposit, so 2nd child will be Neeta
Geeta gets the maximum amount of Bank Deposit, so 3rd child will be Geeta
Seeta will be the 1st child
So, Seeta got Rs. 20 lakhs as Bank Deposit.
Option (C)

Q2)
CAT 2017 – Data Interpretation
We can get the answer to this question with the help of the first one.
Neeta will get 2 flats

Q3)
CAT 2017 – Data Interpretation
Total amount distributed by the old woman = Rs.70 lakh (bank deposits) + Rs.50 lakh (House) + Rs.90 lakhs (3 flats) i.e Rs.210 lakhs + Gold coins worth Rs.1 lakh each.
Ratio of distributed gold coins = 2 : 3 : 4,
Ratio of total assets distributed = 1:2:3
From both the ratios, we can see that
Seeta received 1/3 of the total property and 1/3 of the gold coins. This means her share is 1/3 (Bank deposits + house + flats) = Rs.70 lakhs.
Also, one child got all the three flats but not the house. One child other than Geeta got Rs.30 lakhs in bank deposits. From this we can conclude that Seeta cannot get all the three flats. As her share is Rs.70 lakhs + 1/3 (gold coins).
So, Seeta should receive one house and bank deposits of Rs.20 lakhs. This suggests that Neeta should get Rs.30 lakhs in bank deposits. Therefore, Geeta should get Rs.20 lakhs in bank deposits. From this, all the three flats should be received by Geeta. Let the number of gold coins received by Neeta, Seeta and Geeta be 2x, 3x and 4x respectively.
From these we’ve. (30+2x)/(70+3x) = 1/2 => x = 10
So, number of gold coins must be 90.
Option (B)

Q4)
CAT 2017 – Data Interpretation
Total amount distributed by the old woman = Rs.70 lakh (bank deposits) + Rs.50 lakh (House) + Rs.90 lakhs (3 flats) i.e Rs.210 lakhs + Gold coins worth Rs.1 lakh each
Ratio of distributed gold coins = 2 : 3 : 4,
Ratio of total assets distributed = 1:2:3
From both the ratios, we can see that
Seeta received 1/3 of the total property and 1/3 of the gold coins. This means her share is 1/3 (Bank deposits + house + flats) = Rs.70 lakhs.
Also, one child got all the three flats but not the house. One child other than Geeta got Rs.30 lakhs in bank deposits.
From this we can conclude that Seeta cannot get all the three flats. As her share is Rs.70 lakhs + 1/3 (gold coins).
So, Seeta should receive one house and bank deposits of Rs.20 lakhs. This implies Neeta should get Rs.30 lakhs in bank deposits. Hence Geeta should get Rs.20 lakhs in bank deposits.

Data Interpretation – Set – Applicants for the doctoral programmes

DILR – Data Interpretation – Set

The following set contains four questions related to Data Interpretation. Choose the best answer to each question.

CAT 2017 - LRDI - Data Interpretation - Set - Applicants for the doctoral programmes

Applicants for the doctoral programmes of Ambi Institute of Engineering (AIE) and Bambi Institute of Engineering (BIE) have to appear for a Common Entrance Test (CET). The test has three sections: Physics (P), Chemistry (C), and Maths (M). Among those appearing for CET, those at or above the 80th percentile in at least two sections, and at or above the 90th percentile overall, are selected for Advanced Entrance Test (AET) conducted by AIE. AET is used by AIE for final selection.

For the 200 candidates who are at or above the 90th percentile overall based on CET, the following are known about their performance in CET:

1. No one is below the 80th percentile in all 3 sections.

2. 150 are at or above the 80th percentile in exactly two sections.

3. The number of candidates at or above the 80th percentile only in P is the same as the number of candidates at or above the 80th percentile only in C. The same is the number of candidates at or above the 80th percentile only in M.

4. Number of candidates below 80th percentile in P: Number of candidates below 80th percentile in C: Number of candidates below 80th percentile in M = 4:2:1.

BIE uses a different process for selection. If any candidate is appearing in the AET by AIE, BIE considers their AET score for final selection provided the candidate is at or above the 80th percentile in P. Any other candidate at or above the 80th percentile in P in CET, but who is not eligible for the AET, is required to appear in a separate test to be conducted by BIE for being considered for final selection. Altogether, there are 400 candidates this year who are at or above the 80th percentile in P.

Questions

Q1) What best can be concluded about the number of candidates sitting for the separate test for BIE who were at or above the 90th percentile overall in CET?
A) 3 or 10
B) 10
C) 5
D) 7 or 10

Q2) If the number of candidates who are at or above the 90th percentile overall and also at or above the 80th percentile in all three sections in CET is actually a multiple of 5, what is the number of candidates who are at or above the 90th percentile overall and at or above the 80th percentile in both P and M in CET?

Q3) If the number of candidates who are at or above the 90th percentile overall and also at or above the 80 th percentile in all three sections in CET is actually a multiple of 5, then how many candidates were shortlisted for the AET for AIE?

Q4) If the number of candidates who are at or above the 90th percentile overall and also are at or above the 80th percentile in P in CET, is more than 100, how many candidates had to sit for the separate test for BIE?
A) 299
B) 310
C) 321
D) 330

Answers

Q1: Option (A)
Q2: Answer – 60
Q3: Answer – 170
Q4: Option (A)

Solutions

As per CAT 2017 – Data Interpretation – Set, we can see that, 200 candidates scored above 90th percentile overall in CET. Let the following Venn diagram represent the number of persons who scored above 80 percentile in CET in each of the three sections:
CAT 2017 - Data Interpretation - Set 2 - Applicants for the doctoral programmes
From 1, h = 0.
From 2, d + e + f = 150
From 3, a = b = c
We know, there are a total of 200 candidates,
3a + g = 200 – 150 = 50
From 4, (2a + f) : (2a + e) : (2a + d) = 4 : 2 : 1
So, 6a + (d + e + f) is divisible by 4 + 2 + 1 = 7.
Now, since d + e + f = 150, 6a + 150 is divisible by 7, i.e.,
(6a + 3) is divisible by 7.
Hence, a = 3, 10, 17,. . .
Further, since 3a + g = 50, a < 17. Hence, only two values are possible for a, 3 or 10. We can calculate the values of the other variables for the two cases. a = 3 or 10 d = 18 or 10 e = 42 or 40 f = 90 or 100 g = 41 or 20 From the candidates who are at or above 90th percentile, the candidates who are at or above 80th percentile in at least two sections are selected for AET. Hence, the candidates represented by d, e, f and g are selected for AET. BIE will consider the candidates who are appearing for AET and are at or above 80th percentile in P. Hence, BIE will consider the candidates represented by d, e and g, which can be 104 or 80. BIE will conduct a separate test for the other students who are at or above 80th percentile in P. Given that there are a total of 400 candidates at or above 80th percentile in P, and since there are 104 or 80 candidates at or above 80th percentile in P and are at or above 90th percentile overall, there must be 296 or 320 candidates at or above 80th percentile in P who scored less than 90th percentile overall.
Q1
As per CAT 2017 – Data Interpretation – Set, we can see that, the number of candidates sitting for separate test for BIE who were at or above 90th percentile in CET is either 3 or 10.
Option (A)

Q2
As per CAT 2017 – Data Interpretation – Set, we can see that, as per the given condition, g = 5k. Hence, g = 20. The number of candidates at or above 90th percentile overall and at or above 80th percentile in both P and M = e + g = 60.
Answer: 60

Q3
As per CAT 2017 – Data Interpretation – Set, we can see that, in this case, g = 20. Number of candidates shortlisted for AET = d + e + f + g = 10 + 40 + 100 + 20 = 170
Answer: 170

Q4
As per CAT 2017 – Data Interpretation – Set, we can see that, as per the given condition, the number of candidates at or above 90th percentile overall and at or above 80th percentile in P in CET = 104. The number of candidates who have to sit for separate test = 296 + 3 = 299
Option (A) is the right answer.

The following set contains four questions related to Data Interpretation. Choose the best answer to each question.
CAT 2017 - LRDI - Data Interpretation - Set- A study to look at the early
A study to look at the early teaming of rural kids was carried out in a number of villages spanning three states, chosen from the North East (NE), the West (W) and the South (S). 50 four-year old kids each were sampled from each of the 150 villages from NE, 250 villages from W arid 200 villages from S. It was found that of the 30000 surveyed feds 55% studied in primary schools run by government (G), 37% in private schools (P) white the remaining 8% did not go to school (O).

The kids surveyed were further divided into two groups based on whether their mothers dropped out of school before completing primary education or not. The table below gives the number of kids in different types of schools for mothers who dropped out- of school before completing primary education:
CAT 2017 - Data Interpretation - Set 1 - A study to look at the early
It is also known that:

1. In S, 60% of the surveyed kids were m G. Moreover, in S, all surveyed kids whose mothers had completed primary education were in school.

2. In NE, among the O kids, 50% had mothers who had dropped out before completing primary education.

3. The number of kids in G in NE was the same as the number of kids in G in W.

Answers

Q1: Option (A)
Q2: Option (A)
Q3: Option (A)
Q4: Option (A)

Solutions

As per CAT 2017 – Data Interpretation – Set,
Number of students from NE = 50*150 = 7500
Number of students from W = 50*250 = 12500
Number of students from S = 50*200 = 10000
55% are in G = 16500
37% are in P = 11100
8% did not go to school (O) = 2400
CAT 2017 - Data Interpretation - Set 1 - A study to look at the early

Q1
As per the table deduced from CAT 2017 – Data Interpretation – Set,
Total students in S = 10000
Students from S studying in P = 300 + 3400 = 3700
% = (3700/10000)*100 = 37%
Option (A) is the right answer

Q2
As per the table deduced from CAT 2017 – Data Interpretation – Set,
For W,
Kids whose mothers had completed primary education were not in school = 300
Option (A) is the right answer.

Q3
As per the table deduced from CAT 2017 – Data Interpretation – Set,
Initially, there were 2400 students who were not in school
Now, 1200 of them are in G
The only possibility is 50% of students in W
25% of students in NE
100% of students in S who were not going to school shifted to G.
So, 50% of W = (50/100)*1500 = 750
25% of NE = (25/100)*600 = 150
100% of S = (100/100)*300 = 300
Total = 1200
So, 4200 + 1050 + 750 = 6000 surveyed students were in G in W
Option (A) is the right answer.

Q4
As explained in the previous question, 300 students who were not going to school have now shifted to G.
Of the 5700 students whose mothers had dropped out in the S region, 5400 are in G.
The required percentage = (5400/5700)*100 = 94.7%
Option (A) is the right answer.
