Question

after 18 years Tushar will be 4 times as old as her age now what is his present age​

Answer 1

Let us assume Tushar's present age be x year.

Then, after 18 year, Tushar's age = (x + 18) year

According to the question,

x + 18 = 4x

x – 4x = -18

– 3x = -18

– 3x/3 = (-18/3)

x = 6

Therefore, Tushar's present age is 6 year.

Answer 2

Let present age of Tushar = x

4 times age of = 4x years

after 18 years age will be x+18 years

According to questions

4x = x+18

4x - x = 18

3x = 18

x = 18/3

x = 6

present age of Tushar = x = 6

Thus, Tushar present age is 6 years.
