There are 1550 boys and girls in a school. The number of girls exceeds the number of boys by 500. What is the percentage (to nearest integer) of girls in the school?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 66%.
Let number of boys = x
Then girls = x + 500
x + (x + 500) = 1550
2x + 500 = 1550
2x = 1050
x = 525
So, girls = 525 + 500 = 1025
Percentage of girls = (1025/1550) × 100 ≈ 66%
