Akhil can complete a piece of work in 26 days. Sakshi and Akhil both can complete the same work in 20 days. They started together but Sakshi left after working for 6 days. Find the number of days in which Akhil will complete the remaining work.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 91/5 days.
Akhil can complete a piece of work in 26 days. Sakshi and Akhil both can complete the same work in 20 days
L.C.M(26 and 20) = 260
The efficiency of Akhil = 260/26 = 10 units
The efficiency of Akhil and Sakshi = 260/20 = 13 units
The efficiency of Sakshi = 13 - 10 = 3 units
Now, according to the question
They worked together for 6 days = 6 × 13 = 78 units
Remaining work = 260 - 78 = 182 units
Akhil can complete in = 182/10 = 91/5 days
