Question

after 12 year manoj will be 13 times be old as old as he was 4 years ago. find its current age

Answer 1

Let the age of Manoj be x.

Before 4 years: he will be x - 4.

Given that x + 12 = 13(x - 4).

                  x + 12 = 13x - 52

                  12x = 64

                  x = 64/12.

Answer 2

Let the current age of manoj be X. X+12=13(X-4). X+12=13X-52. X-13X=-52-12. -12X=-64. X=64/12=5.33 years
