The total number of children from villages V4 and V5 together is approximately what percentage more than the total number of children who do not attend school from the same two villages?

A118
B124
C122
D120 ✓ Correct
Correct answer: (D) 120
Explanation

The excess is about 120%, so the answer is 120.

Children in V4 and V5 are 18% plus 31% of 5800, which is 49% of 5800, giving 2842.

Children attending school from V4 and V5 are 21% plus 22% of 3600, which is 43% of 3600, giving 1548.

Children not attending school from these two villages are 2842 minus 1548, which is 1294.

The excess is 2842 minus 1294, which is 1548.

The percentage more is 1548 divided by 1294 times 100, about 119.6, which rounds to 120.

Non-attending children are found by subtracting the school-going count from the total for the same villages.
