Me. Sharma is twice as his son.after4year he is 4 times old as his son was 9 year.how old are they

Answer 1

Step-by-step explanation:

Let the son's age be x and Mr Sharma's age be 2x.

After 4 years Mr Sharma will be = 2x+4

His son's age 9 years ago= x-9

4(x-9) = 2x+4

4x-36 = 2x+4

2x = 40

x = 20

Therefore, Mr Sharma is 40 years old and his son is 20 years old now.
