Question

After 12 years Kanwar shall
be there times as old as he
was four year ago,
Find his
present age ?​

Answer 1

let the present age of kanwar be x

the age of Kanwar 4 years ago was 4 years old

three times of his age is 3x

after 12 years his age is 4×3x+12

solution —

x = 4 × 3x + 12

x = 12x + 15

x–12x = 15

x + x. = 15/ –12

2x. = 5 / –4

x = 5 /–4 ×2

x. = 5 / –8
