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:

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.

Q1: Option (A)

Q2: Option (A)

Q3: Option (A)

Q4: Option (A)

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

Total students in S = 10000

Students from S studying in P = 300 + 3400 = 3700

% = (3700/10000)*100 = 37%

Option (A) is the right answer

For W,

Kids whose mothers had completed primary education were not in school = 300

Option (A) is the right answer.

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.

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.
