Sameer can complete the work in 16 days. In how many days will the work be completed by Ajay, if his efficiency is 60% more than that of Sameer?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10 days.
Sameer : Ajay efficiency = 100 : 160 = 5 : 8
Time ∝ 1/efficiency
So,
Time ratio (Sameer : Ajay) = 8 : 5
Given that Sameer takes 16 days
⇒ Ajay = 16 × = 10 days
