Best answer
Correct Answer - Option 3 : 10 days

Given

Arjun completes (5/7)th of work in 25 days.

Calculation

Let the number of days requires to complete the remaining work is x days

Remaining work = [1 - (5/7)]

⇒ (7 - 5)/7

⇒ 2/7

(5/7) : (2/7) : : 25 : x

⇒ (5/7) × x = (25) × (2/7)

⇒ x = (25 × 2)/5

⇒ x = 10

∴ 10 days are required to complete the remaining work.
