Question

Bhaskar is 4 times as old his son After 16 years we will be twice as old as his son find his son's present age

Answer 1

If son's age = x
then, Bhaskar's age = 4x
After 16 years!
Son's age = x+16
Bhaskar's age = 4x+16

Now, According to Ques,
4x+16 = 2(x+16)
4x+16 = 2x+32
2x = 16
x = 8
That is your answer!

Answer 2

let the age of Bhaskar is 4x and the son's age =x

after 16years ,let Bhaskar age will be 2y and son age is y

converting in equation,

4x+16=2y -------1equation * 1
x+16=y --------2equation*4

4x+16=2y
4x+64=4y
- - -

-48=-2y

24=y

then put the value of y in -------2equation

x+16=24

x=24-16=8

x=8

son age =8years
and
Bhaskar age =8*4=32years




I hope this will help you
