VI B? Find the number of girls in VI A.
​

Answer 1

Answer:

Answer is 15

Step-by-step explanation:

Let the total number of students=100

Ratio of boys and girls=2:3

2+3=5

No. of boys = 2/5 x 100 = 40

No. of girls = 3/5 x 100 = 60

If 20% of the boys leaves the class then 20% of 40

20/100 x 40 = 8

Now number of boys=40−8=32

New ratio= 32:60 ⇒ 18:15
