On the basis of the figure below answer the following question. In the graph, the number of boys and girls are given in five schools. Study this graph properly and answer the questions.
What percentage will be the number of girls in school A out of the total number of girls in all the schools?
- A.
15
- B.
12
- C.
56
- D.
34
Show answer & explanation
Correct answer: A
To find what percentage a category contributes to a combined total drawn from several groups, use the percentage-share formula: Percentage share = (value for that category ÷ sum of the values for all groups) × 100. Here this means dividing the number of girls in School A by the total number of girls across all five schools, then multiplying by 100.
Read the number of girls for each school from the line graph: School A ≈ 2750, School B ≈ 4000, School C ≈ 3500, School D ≈ 4250, School E ≈ 3250.
Add these five values to get the total number of girls across all schools: 2750 + 4000 + 3500 + 4250 + 3250 = 17750.
Divide the girls in School A by this total and multiply by 100: (2750 ÷ 17750) × 100 ≈ 15.5%.
Matching this to the closest whole-number option gives approximately 15%.
Cross-check: with five schools sharing the total girls equally, each would hold about 20%. School A's point on the graph lies below the average level for girls, so its true share must be under 20% — consistent with 15%, and it rules out the much larger values (56% and 34%), which could only arise from dividing by an incorrect, far smaller denominator.
