Question: Afroza is 10 years younger than Firoza. If in 5 years, Firoza will be twice as old as Afroza. How old will Afroza be in 3 years?

Solution:
Let Afroza's current age be x years.
So, Firoza's current age is (x + 10) years.
In 5 years:
Afroza's age will be (x + 5) years.
Firoza's age will be (x + 10 + 5) = (x + 15) years.

According to the question,
x + 15 = 2(x + 5)
⇒ x + 15 = 2x + 10
⇒ 2x - x = 15 - 10
⇒ x = 5
So, Afroza's current age is 5 years.
In 3 years, Afroza's age will be = 5 + 3 = 8 years.
∴ Afroza will be 8 years old in 3 years.

Correct Answer: ঘ) 8
