Answer»

Quantity A:

Let present age of Son be x

⇒ Present age of FATHER = 3x

Now, 5 years ago

⇒ Father’s age = 3x – 5

⇒ Son’s age = x – 5

According to QUESTION,

⇒ x – 5 = (1/5) × (3x – 5)

5X – 25 = 3x – 5

⇒ 2x = 20

⇒ x = 10

⇒ Father’s present age = 3x = 3 × 10 = 30 years

∴ Present age of mother = 30 – 5 = 25 years

Quantity B: 30

Quantity A < Quantity B
