Question

Father's present age is 4 times Kunal's age. After 5 years, father's age will be 3 times Kunal's age, then the present age of Kunal is

Answer 1

Let age of Kunal = x

Then,

Age of Father = 4x

After 5 years...

Age of Kunal = x+5

Age of father = 4x+5

After 5 years, father's age will be 3 times Kunal's age

So,

3(x+5) = 4x+5

3x+15 = 4x +5

3x+10 = 4x

4x - 3x = 10

x = 10

Present age of Kunal Is 10

Hope this will help...
