Question

In a school, the ratio of number of boys to the
number of girls is 9:7 Find the number of boys and girls

if the total number of students is 3200​

Answer 1

Step-by-step explanation:

Let the number of girls be 7x and number of boys be 9x.

7x+9x = 3200

16x= 3200

x=3200/16

x=200

Number of girls= 7x= 7×200= 1400

Number of boys = 9x= 9×200= 1800

Answer 2

Solution:

Ratio of boy and girls is 9:7

Let boys= 9x and girls= 7x A/Q

9x + 7 = 3200

16x = 3200

x = 3200/16 = 200

So boys= 9x 200 = 1800
