The ratio between the present ages of Azad and Mehar is 5 ∶ 4 respectively. The ratio between Azad’s age 3 years ago and Mehar’s age 3 years hence is 1 ∶ 1. What is the ratio between Azad’s age 2 years hence and Mehar’s age 2 years ago? Correct Answer 16 ∶ 11
Given∶
The ratio between the present ages of Azad and Mehar is 5 ∶ 4.
The ratio between Azad’s age 3 years ago and Mehar’s age 3 years hence is 1 ∶ 1.
Formula Used∶
Concept of Ratio
Calculation∶
The ratio of present ages of Azad and Mehar = 5 ∶ 4
Let Azad’s Present age be 5a and Mehar’s present age be 4a
3 years ago, Azad age = (5a – 3) years
3 years hence, Mehar’s age = (4a + 3) years
According the question,
(5a – 3) ∶ (4a + 3) = 1 ∶ 1
⇒ a = 6
So, the present age of Azad = 5a = 5 × 6 = 30 years
And the present age of Mehar = 4a = 4 × 6 = 24 years
After 2 years, Azad’s age will be = 30 + 2 = 32 years
2 years ago, Mehar’s age was = 24 – 2 = 22
The required ratio = 32 ∶ 22 = 32/22 = 16 ∶ 11
∴ 16 ∶ 11 is the required ratio.
