Ages — connecting three people across two relations: Manoj:Wasim = 3:11 now. Wasim is 12 years younger than Rehana, and Rehana will be 85 after 7 years. Find the present age of Manoj’s father who is 25 years older than Manoj.

Introduction / Context:
This chain problem links Manoj to Wasim, Wasim to Rehana, and then adds a fixed offset for Manoj’s father. Work backward from Rehana.

Given Data / Assumptions:

• Rehana in 7 years = 85 ⇒ Rehana now = 78.
• Wasim is 12 years younger than Rehana ⇒ Wasim = 66.
• Manoj:Wasim = 3:11 ⇒ Manoj = (3/11)*66 = 18.
• Manoj’s father = Manoj + 25.

Concept / Approach:
Sequential substitution from the farthest known (Rehana’s future) to the target (Manoj’s father).

Step-by-Step Solution:

Verification / Alternative check:

Why Other Options Are Wrong:

• 67, 45, 69 conflict with the chain of deductions.

Common Pitfalls:

• Taking “12 years younger” in the wrong direction.
• Using 85 as Rehana’s current age instead of future age.

Final Answer:
