प्रश्न

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

बेरीज

उत्तर

Let Neetu’s age = x years

3 times Neetu’s age = 3x years

Fifteen more than 3 times Neetu’s age = (3x + 15) years

4 times Neetu’s age = 4x

According to the statement :

4x = 3x + 15

⇒ 4x – 3x = 15

⇒ x = 15

Neetu’s age = 15 years
