Expert Answer:

Let papa's present age = x yrs

Let mymmy's present age = y yrs

20 yrs ago, papa's age = x-20, mummy's age = y-20

Given: (x-20+y-20) / 2 = 23

That is (x+y-40)= 46

x+ y = 86

Let your present age = z yrs

Given: (x+y+z) / 3 = 34

(86+z) / 3 = 34

86+z = 102

Hence, z = 16

So, your present age = 16 yrs
