Question

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

Answer 1

Answer:

Your present age is 12 years

Step-by-step explanation:

let your present age be x,

after 12 years, your age = x+12

4 years ago, your age = x-4

ATQ,

x+12 = 3(x-4)

x+12 = 3x - 12

x-3x = -12-12

-2x = -24

x = (-24)/(-2)

x = 24/2 = 12 years
