## Question

Consider three mixtures – the first having water and liquid A in the ratio 1 : 2, the second having water and liquid B in the ratio 1 : 3, and the third having water and liquid C in the ratio 1 : 4. These three mixtures of A, B, and C, respectively, are further mixed in the proportion 4:3:2. Then the resulting mixture has

A) The same amount of water and liquid B
B) The same amount of liquids B and C
C) More water than liquid B
D) More water than liquid A

Option (C)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Mixtures, we can see that,
Ratio of water in 1st mixture = 1/3
Ratio of A in 1st mixture = 2/3
Ratio of water in 2nd mixture = 1/4
Ratio of B in 2nd mixture = 3/4
Ratio of water in 3rd mixture = 1/5
Ratio of C in 3rd mixture = 4/5
The mixtures are divided in the ratio 4:3:2
So, water according to this composition = 4/9 * 1/3 + 3/9 * 1/4 + 2/9 * 1/5 = 149/540 = 0.27
Solution A in the composition = 4/9 * 2/3 = 8/27 = 0.29
Solution B in the composition = 3/9 * 3/4 = 9/36 = 0.25
Solution C in the composition = 2/9 * 4/5 = 8/45 = 0.17
We can see that Option C is correct

## Question

Amal can complete a job in 10 days and Bimal can complete it in 8 days. Amal, Bimal and Kamal together complete the job in 4 days and are paid a total amount of Rs 1000 as remuneration. If this amount is shared by them in proportion to their work, then Kamal’s share, in rupees, is

A) 100
B) 200
C) 300
D) 400

Option (A)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Time and Work, we can see that,
Amount of work done by Amal in 1 day = 1/10
Amount of work done by Bimal in 1 day = 1/8
Amount of work done by Kamal in 1 day = 1/k
All of them together can complete a work in 4 days. So,
1/10 + 1/8 + 1/k = ¼
On solving, we get, k = 40
Ration of work done by them = 1/10: 1/8: 1/40 = 4:5:1
Ratio of work done by Kamal = 1/10
Amount received by Kamal = 1000/10 = 100
Option (A)

## Question

A motorbike leaves point A at 1 pm and moves towards point B at a uniform speed. A car leaves point B at 2 pm and moves towards point A at a uniform speed which is double that of the motorbike. They meet at 3:40 pm at a point which is 168 km away from A. What is the distance, in km, between A and B?

A) 364
B) 378
C) 380
D) 388

Option (B)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Time Speed and Distance, we can see that,
Speed of motorbike = s
Speed of car = 2s
Distance covered by motorbike in 1 hr = s km
Motorbike takes 2hrs 40 mins to reach the point where both car and motorbike meet.
In 2 hrs 40 mins, motorbike will cover a distance of 8s/3 = 168. So, s = 63
Since, speed of car is double than motorbike. So,
Distance covered by car in 1 hr 40 mins = 2 * Distance covered by motorbike in 1 hr 40 mins
Distance covered by motorbike in 1 hr 40 mins = 105 km
Distance covered by car in 1 hr 40 mins = 210 km
So, total distance = 168 + 210 = 378 km

## Question

If a, b, c are three positive integers such that a and b are in the ratio 3 : 4 while b and c are in the ratio 2:1, then which one of the following is a possible value of (a + b + c)?

A) 201
B) 205
C) 207
D) 210

Option (C)

## Solution

From CAT 2017 – Quantitative Aptitude – Number Systems, we can see that,
Let us take a = 3x and b = 4x
Also, b = 2y and c = y
4x = 2y => y = 2x
Now, c = 2x
a + b + c = 9x
Since it is a multiple of 9. From the given options we have to find the one that is divisible by 9. 207 satisfies this condition.
Option (C)

## Question

In a village, the production of food grains increased by 40% and the per capita production of food grains increased by 27% during a certain period. The percentage by which the population of the village increased during the same period is nearest to

A) 16
B) 13
C) 10
D) 7

Option (C)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Percentages, we can see that,
The total production of food grains (Initial) = t
The total production of food grains (Final) = t’ = 1.4t
Population (Initial) = n
Population (Final) = n’
Per capita food production (Initial) = t/n
Per capita food production (Final) = t’/n’ = 1.4t/n’
1.4t/n’ = t/n
=> n’ = 140n/127
Population increased by [(140n/127 – n)/n] * 100 = 10% (Approximately)
Option C is the right answer.

## Question

Mayank buys some candies for Rs 15 a dozen and an equal number of different candies for Rs 12 a dozen. He sells all for Rs 16.50 a dozen and makes a profit of Rs 150. How many dozens of candies did he buy altogether?

A) 50
B) 30
C) 25
D) 45

Option (A)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Profit and Loss, we can see that,
Number of candies he bought of type 1 = n
Number of candies he bought of type 2 = n
Total candies = 2n
SP = 16.5 * 2n =33n
CP = 12n +15n = 27n
Profit = SP-CP = 6n = 150
n = 25
Total candies = 2n = 50

## Question

A tank has an inlet pipe and an outlet pipe. If the outlet pipe is closed then the inlet pipe fills the empty tank in 8 hours. If the outlet pipe is open then the inlet pipe fills the empty tank in 10 hours. If only the outlet pipe is open then in how many hours the full tank becomes half-full?

A) 20
B) 30
C) 40
D) 45

Option (A)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Pipes and Cisterns, we can see that,
The time in which inlet pipe can fill tank (a) = 8 hrs
Time in which outlet pipe can empty the tank = b
1/a – 1/b = 1/10
On solving, we get b = 40 hrs
Half of the tank will be empty when b=20 hrs

## Question

The manufacturer of a table sells it to a wholesale dealer at a profit of 10%. The wholesale dealer sells the table to a retailer at a profit of 30%. Finally, the retailer sells it to a customer at a profit of 50%. If the customer pays Rs 4290 for the table, then its manufacturing cost (in Rs) is

A) 1500
B) 2000
C) 2500
D) 3000

Option (B)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Profit and Loss, we can see that,
Cost Price (CP) of manufacturer = CP
Selling Price(SP) of manufacturer = 1.1CP = CP (Dealer)
SP (Dealer) = 1.3 * 1.1 CP = CP (Retailer)
SP (Retailer) = 1.5 * 1.3 * 1.1 CP = CP (Customer)
It is given that,
1.5 * 1.3 * 1.1 CP = 4290
On solving, we get, CP = 2000

## Question

The average height of 22 toddlers increases by 2 inches when two of them leave this group. If the average height of these two toddlers is one-third the average height of the original 22, then the average height, in inches, of the remaining 20 toddlers is

A) 30
B) 28
C) 32
D) 26

Option (C)

## Solution

From CAT 2017 – Quantitative Aptitude – Arithmetic – Averages, we can see that,
Average of 22 people = a/22
Let sum of heights of two people who left = x
From the question,
(a-x)/20 = a/22 + 2
On solving, we get x=a/33
Putting value of x in a, we get the value of a as 660
x=20
Average height of remaining 20 toddlers = (a-x)/20 = 32
