Answer:
Number of girls = 600
Step by step explanation:
Number of boys = 400
No. of girls = 3/5
No. of boys in fraction = 2/5 ( total - no. of girls = 5/5 - 3/5 = 2/5)
Then, girls : boys (ratio) = 3 : 2
Let the no. of girls be 3x and boys be 2x
Then ,
2x = 400 (no. of boys)
x = 400/2 = 200
x = 200
∴ no. of girls = 3x = 3 × 200 = 600
