Answer 1

Step-by-step explanation:

let age of John = x yrs

age of Dravid= x-16 yrs

6 years ago

age of John =(x -6 )yrs

age of David= x-16-6= (x-22 )yrs

David age was thrice of that John's = 3(x -22) yrs

A. T. P

( x -6)= 3(x-22)

x-6 = 3x -66

x-3x = -66+6

-2x = -60

x = 30

therefore age of David= 30 -16 = 14 yrs

age of John = 30 yrs
