Answer 1

$\mathfrak{\huge{The\:Correct\:Question:}}$

A boy said:- My age 3 years hence, multiplied by 3, and from that, subtract 3 times my age, 3 years ago. This will give you my exact present age.

Find the age of the boy.

$\mathfrak{\huge{Answer:}}$

Let the present age of the boy = x

According to the given question:

=》 (x + 3)3 - 3(x - 3) = x

Solve this formed equation further

=》 3x + 9 - 3x + 9 = x

Some more steps to go

=》 9 + 9 = x

Age of the boy :

=》 x = 18 years

Thus, the final answer will be $\tt{\huge{18\:years}}$
