Question

After 6 years I shall be 3 times old as I was 4 years ago.Find my present age
​

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

let present age =x

age 4 years ago =x-4

age 6 years later =x+6

According to question

x+6=3 (x-4)

x+6=3x -12

3x-x=12+6

2x=18

x=9

Therefore Present age =9 yrs
