Question

After 18 years Tushar will be 4 times as old as her age now. What is his present age?
​

Answer 1

Answer:

x+18=4x This is the formula for the answer

Answer 2

This is what question says “ In 20 years' time, Tushar will be four times the age he was four years ago.”

So in 20 years, means in coming 20 years from his present age 'x', he will be 4 times the age he was 4 years ago ‘x-4'.

which means that

• From present age till next 20 years, Tushar’s age will be ‘x+20′.

•. And which is equals to 4 times of age of what Tushar was 4 years back from present age. So

x + 20 = 4(x -4)

x + 20= 4x -16

3x=36

x=12

So the present age of Tushar is 12.
