Question

Fifteen more than 3 times neethu's age is the same as 4 times her age. How old is she?

Answer 1

Hello dear!

Let Neethu's age be x.

Fifteen more than three times Neethu's age = 3x + 15

Four times Neethu's age = 4x

Now according to question,
$3x + 15 = 4x$
Exchanging LHS and RHS,
$4x = 3x + 15 \\ 4x - 3x = 15 \\ x = 15$

So,
Neethu is 15 years old.

Answer 2

Hey mate.
Here is your answer-

Let neethu's age be x
3 times her age = 3x
15 more than 3 times her age = 3x+15

A.T.Q Fifteen more than 3 times Neethus's age is the same as 4 times her age.

i.e. 3x+15=4x
=> 15 = 4x-3x
=> 15 = 1x
=> or x = 15

Therefore, Neethu is 15 years older.

Hope it helps!!!!!
