Mr. A and Mr. B can do a piece of work in 8 and 12 days respectively. If both of them work together, in how many days the work will get completed ?
Answer with explanationAnswer: Option C
A ‘s 1-day work = 1/8 B’s 1-day work = 1/12
When both work together, 1 day’s work = (1/8) + (1/12) = (3+2)/24 = 5/24
Number of days to complete the work will be 24/5 days
