Question

the ratio of boys and girls in a school is 5:2.the total number of student in the school is 2100. find the number of boys and girls

Answer 1

Ratio of boys & girls = 5:2

Let the strength of boys = 5x

and the strength of girls = 2x

5x + 2x = 2100

7x = 2100

x = 2100÷7

x = 300

Strength of boys = 5x

Boys = 5×300

Boys = 1500

Strength of girls = 2x

Girls = 2 × 300

Girls = 600
