If in a class, 10% of the girls are equal to one-fourth of the boys in the school, then the ratio of girls to the boys in the school is?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 5:2
Let the number of girls = G and boys = B.
Given:
$10\% \text{ of girls} = \frac{1}{4} \text{ of boys}$
$\frac{10}{100}G = \frac{1}{4}B$
$\frac{G}{10} = \frac{B}{4}$
Cross-multiply:
$4G = 10B$
$2G = 5B$
$\frac{G}{B} = \frac{5}{2}$
Correct answer: 5 : 2
