Hey !

Given,

The ages of of bhanu and indu are in the ratio 3:5.

Let the Present age of Bhanu be 3x

and Present age of Indu be 5x

After 10 years, the ratio of their ages will be 11:15.

After 10 years,

Age of Bhanu = 3x+10

Age of Indu = 5x +10

At this time, their ratio of ages is 11:15

=> (3x +10)/(5x+10) = 11x/15x

=> 15x(3x+10) = 11x(5x+10)

=> 45x²+150x = 55x²+110x.

=> 10x² = 40 x

=> 10x = 40

=> x = 4.

•°• Present age of Bhanu = 3x = 12 years

& Present age of Indu = 5x = 20 years.

Validation:

Ratio of their present ages :

12 : 20 = 3 : 5

After 10 years,

Ratio of their ages :

22 : 30 = 11 : 15
