Question

After 12 years Aman shall be 3 times as old as he was 4 years ago find his present age

Answer 1

Hi...☺

Here is your answer...✌

Let the present age of Aman be x years

Then,
Aman's age after 12 years = (x + 12) years

Aman's age 4 years ago = (x - 4) years

Now,
According to the question,

x + 12 = 3(x - 4)

x + 12 = 3x - 12

x - 3x = - 12 - 12

-2x = -24

=> 2x = 24

=> x = 12

Hence,

Present age of Aman is 12 years

Answer 2

A+12=3(A-4)
A+12=3A-12
4A=24
A=6 years
