Q1.After 12 years I shall be 3 times as old as I was 4 years ago . find my present age .

Answer 1

Dear student , here is detailed solution to your query

Let , your Present age be = x
Age 4 years ago = x-4
Age after 12 years = x+12

Given that : Age after 12 years = 3 ( Age 4 years ago )
=> ​​​​​ x +12 = 3 ( x-4)
=> x + 12 = 3x - 12
=> 2x = 24
=> x = 12.

​​​​​​Therefore Present age = 12 years.
