x=12

Answer 2

Given :

• after 12 years kanmar shall be 3 times as old as he was 4 years ago

To find :

• his present age

Solution :

Let Kanwar's present age be x yr

After 12 yr, Kanmar's age = (x + 12)y

and 4 yr ago, Kanmar's age = (x -4)yr

ACcording to the question,

x + 12 = 3 (x - 4)

x + 12 = 3 x -12

3x - x = 12+ 12

2x = 24

x = 24/2

x = 12

Hence, Kanmar s present age is 12 yr.
