Direction : The Line graph shows the number of people (Boys + girls) visited five (A, B, C, D & E) different parks and the number of girls visited out of total people visited these five parks. Read the data carefully and answer the questions.
Total people (Boys + Girls) who visited park B is what percent more than total people (Boys + Girls) who visited park E (Approximate)?
- A.
25%
- B.
39%
- C.
43%
- D.
33%
- E.
66%
Show answer & explanation
Correct answer: D
Concept: To find how much percent quantity X is MORE THAN quantity Y, the reference (base) is always the quantity that comes after “than” — here that is Y. The formula is: percent more = ((X − Y) ÷ Y) × 100. The base is Y, not X, and not their sum.
Reading the values from the (Boys + Girls) line for the two parks asked:
Park B total (Boys + Girls) = 72
Park E total (Boys + Girls) = 54
Application — substitute B as X and E as the base Y:
Difference = 72 − 54 = 18
Percent more = (18 ÷ 54) × 100
= (1 ÷ 3) × 100 = 33.33% ≈ 33%
Cross-check: if 72 were 33.33% more than the base, the base × (1 + 1/3) should give 72. Indeed 54 × 4/3 = 72, which confirms the result. Note the base is E (54); using B (72) as the base instead would answer a different question (“E is what percent less than B”).
