Answer 2

Step-by-step explanation:

Let the ages of Anjali and Ashu be 2x and 3x respectively

5years hence their ages will become (2x+5)(3x+5)

After 5years the ratio of ages is 3:4

so we get equation

2x+5÷3x+5=3/4

2x+5÷3x+5=3/4

(2x+5)×4=(3x+5)×3

(cross multiplication)

8x+20=9x+15

8x-9x=15-20

-x=-5(negative gets cancelled)

x=5

So the present age of Anjali =2×5=10y

and the present age of Ashu =3×5=15yr
