The ratio of number of boys and girls in a school of 3528 students is 5:4. How many more girls should be admitted in the school to make this ratio 1:1?
Given:
Total students = 3528
Ratio of boys : girls = 5 : 4
Find how many more girls should be admitted to make the ratio 1 : 1.
Solution:
Total parts = 5 + 4 = 9
Value of one part =
Number of boys =5 × 392 = 1960
Number of girls = 4 × 392 = 1568
To make the ratio 1:1, number of girls must equal number of boys:
Required girls = 1960
Additional girls needed = 1960-1568 = 392
