Question

After 12 years, I shall be 3 times as old as 4 years ago, my present age is? ​

Answer 1

Answer:

12 years

Step-by-step explanation:

let the present age be x

Age after 12 years=x+12

Age before 4 years=x-4

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

x+12= 3x-12

24=3x-x

24=2x

x=12

Answer 2

Answer:

let present age is x then after 12 years your age is x+12

x+12=3x(x-4)

x+12=3x-12

2x=24

x=12
