Question

After 12 years suraj will be 3 times of he was 4 years ago what is present age

Answer 1

let present age be X. Then,

x+12 = 3 (x - 4)
=> x + 12 = 3x - 12
=> 24 = 2x
=> x = 12

Hence, present age is 12 yrs.

Answer 2

Let the present age of Suraj be x

After 12 years age = ( x + 12 )

Four years ago Suraj's age = ( x - 4 )

3 times of he was 4 years ago = 3( x - 4 )

A/Q,

(x + 12) = 3(x - 4)

x + 12 = 3x - 12

x - 3x = 12 + 12

2x = 24

x = $\frac{24}{2}$

x = 12

$\therefore{}$ $\blue {The \: present \: age \: of \: Suraj \: is \: 12 \: years}$
