Akhil can complete a piece of work in 24 days. Shyam can complete the same piece of work in 12 days. If both of them work together, in how many days can they complete the same piece of work?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is opton 4 i.e. 8 days
Time required for Akhil to complete the work = 24 days
So, Akhil's work per day = 1/24 of the work
Time required for Shyam to complete the work = 12 days
Shyam's work per day = 1/12 of the work
Akhil and Shyam's work per day = (1/24) + (1/12) = 1/8 of the work
Time required for Akhil and Shyam together = 1/(1/8) = 8 days
Therefore, Akhil and Shyam can complete the work together in 8 days.
