Question: Arko is twice as old as Adeeb. Eight years ago, Arko was 6 years younger than three times Adeeb's age at that time. How old will Arko be in 5 years?

Solution:
Let Adeeb's age = x,
then Arko's age = 2x.

8 years ago:
Arko was 2x - 8 and Adeeb was x - 8.

According to the question,
2x - 8 = 3(x - 8) - 6
⇒ 2x - 8 = 3x - 24 - 6
⇒ 2x - 8 = 3x - 30
⇒ x = 22

Arko's current age = 2x = 2 × 22 = 44.
∴ In 5 years, Arko will be = 44 + 5 = 49.
