Answer 1

..........................

Answer 2

Step-by-step explanation:

Let the age of Raju = x years

then the age of Ritu = 4 × x years = 4x years

In 4 years time,

age of Raju = (x +4) years

age of Ritu = (4x + 4) years

According to given problem,

4x + 4 = 2 (x + 4)

⇒ 4x + 4 = 2x + 8

⇒ 4x – 2x = 8 – 4

⇒ 2x = 4 ⇒ x = 42

⇒ x = 2

Hence, the age of Raju = 2 years

and the age of Ritu = 4 × 2 years = 8 years
