Question: A and B can complete a work in 12 days and 15 days respectively. If they work together, how many days will they take to complete the work?
Options:
Correct Answer: 8 days
Solution:
A\'s work rate = 1/12, B\'s work rate = 1/15. Combined work rate = 1/12 + 1/15 = 5/60 = 1/12. Time taken = 12 days.
