Question

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

Answer 1

Let your present age be x years.

After 12 years it will be x + 12.

Given that I shall be 3 times as old I was 4 years ago.

x + 12 = 3(x - 4)

x + 12 = 3x - 12

3x - x = 12 + 12

2x = 24

x = 12.


Therefore Your present age = 12 years.


Hope this helps!

Answer 2

let my present age be x. after 12 years my age will be x+12 therefore four years ago my age will be x-4. so equation become like this. x+12=3(x-4) that is x+12=3x-12. by solving 3x-x=12+12. hence 2x=24 so x=12
