If 'A' can complete a work in 12 days and 'B' is 60% efficient than that of 'A',then in how many days 'B' can do the same work?
AnswerClick to flip back
A
7.5
💡 Explanation:
If A takes 12 days, then B's efficiency being 60% more means B works at 1.6x A's rate. So B takes 12/1.6 = 7.5 days. The phrase '60% efficient than that of A' is slightly awkward but mathematically leads to option B.
