A can complete a work in 8 days and B can complete the same work in 11 days. How long will they take, if both work together?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 4 days
Given that
A * 8 = B * 11
A/B = 11/8
Total work = 11 * 8 = 88 days
They will take if both work together = 88/(11 + 8) = 88/19 = 4 days
