Best answer
Correct Answer - Option 2 : 36 days

Given

Mr. Kunal efficiency = 2(Mr. Aman's efficiency)

Concept used:

Efficiency is inversely proportional to Time

Calculation

Let the Mr. Aman completes a work in x days

Then, Kunal completes in (x/2) days

According to question∶

⇒ x - (x/2) = 18

⇒ x/2 = 18

⇒ x = 36 days

∴ Mr. Aman completes a work in 36 days.
