Question

After 12 yrs , kanwar shall be 3 times old as he was four years ago , find his present age

Answer 1

Answer:

Let x = present age

x + 12 will be my age 12 years from now.

3(x-4) will be three times as old as I was 4 years ago

x+12 = 3(x-4)

Solve for x

x+12 = 3x - 12

subtract x from both sides

12 = 2x - 12

add 12 to both sides

24 = 2x

divide both sides by 2

12 = x

The present age men is 12 years
