Question

Shobo's mother's present age is 6 times Shobo's present age. Shobo's age 5 years from now will be one third his mother's age. What are their present age?

Answer 1

Answer:

10 / 3 yrs and 20 yrs

Step-by-step explanation:

Let present age of Shobo be x

∴ present age of Shobo's mother is 6x

After 5 yrs,

Shobo's age = x +5 yrs

Shobo's mother's age = 6x +5 yrs

ATQ,

x + 5 = 1/3 ×(6x +5)

⇒ (x + 5) × 3 = 6x +5

⇒ 3x + 15 = 6x + 5

⇒ 3x = 10 ⇒ x = 10 / 3 yrs

∴ 6x = 10 / 3 × 6 = 20 yrs
