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.
