Question

A mother is now three times as old as her daughter. 5 years ago, she was four times as old as her daughter. What is the current age of the daughter?

पर्याय

• 12 years

• 20 years

• 16 years

• 15 years

Answer 1

15 years

Explanation:

Let the current age of the daughter be x.

∴ The mother's current age = 3x

5 years ago,

Age of daughter = (x – 5) years

Age of mothers = (3x – 5) years

We know,

(3x – 5) = 4(x – 5)

⇒ 3x – 5 = 4x – 20

⇒ x = 15

∴ Age of the daughter = 15 years.
