Answer 1

Let his present age be x. [4 yrs ago,] his age = x-4 yrs. [After 12 years] his age = 12+x ; also, it will be thrice his age 4 years ago, i.e. 3(x-4) years. So, reqd. age ---- 12+x=3(x-4) => 12+x=3x-12 =>24=2x => 12=x. So, his present age is 12 years.

Answer 2

Answer:

12

Step-by-step explanation:

Let the present age of Kanwar be x

Age after 12 years = x+12

Age 4 years ago = x-4

Now we are given that after 12 years Kanwar will be 3 times as old as he was 4 years ago

So, $x+12=3(x-4)\\x+12=3x-12\\24=2x\\x=\frac{24}{2}\\x=12$

Hence the present age of Kanwar is 12
