Question

1) In a school of 3600 students, number of boys is twice the number of girls. Find the number of girls.

Answer 1

Answer: 1200

Step-by-step explanation:

x is the number of boy

The number of boys is twice the number of girls: $\frac{1}{2} x$

Total is 3600 students: x + $\frac{1}{2}x$= 3600 → x = 2400

Therefore, the number of girls is: 2400/2= 1200

Answer 2

Answer: There are 2400 boys and 1200 girls

Step-by-step explanation:

x represents girls

2x represents boys

________________________

x+2x=3600

3x =3600

x=3600/3

x =1200

Number of girls = 1200

1200 * 2 = 2400
