Answer 2

Answer:

let age of ,

ram = x , shyam = y , john = z

before 5 years,

ram = x-5 , shyam = y-5 , john = z-5

average age = { (x-5) + (y-5) + (z-5) }/3

16 = [x+y+z-15]/3

48 = x+y+z-15

x+y+z = 63

after 5 years

ram = x+5, shyam = x+5, john = x+5

average age = { (x+5) + (y+5) + (z+5) }/3

= (x+y+z+15)/3

= (63+18)/3

= 26
