The ratio of the ages of Minu and Meera is 4 : 2. If the sum of their ages is 6 years, find the ratio of their ages after 8 years.

Question: The ratio of the ages of Minu and Meera is 4 : 2. If the sum of their ages is 6 years, find the ratio of their ages after 8 years.

Solution:
Let the age of Minu is 4X and age of Meera 2X.

As per question,
4X + 2X = 6
⇒ 6X = 6
∴ X = 1

∴ Minu's age = 4 × 1 = 4 years
∴ Meera's age = 2 × 1 = 2 years

Ratio of their ages after 8 years;
= (4 + 8) : (2 + 8)
= 12 : 10
= 6 : 5
