60. A can do a certain job in 12 days. B is 60% more efficient than A. How many days does B alone take to do the same work?
a) 13/2 days
b) 15/2 days
c) 17/2 days
d) 19/2 days
Answer:
b) 15/2 days
Explanation:
The ratio of their efficiencies is A:B = 100:160 = 5:8. Time taken is inversely proportional to efficiency, so the ratio of time is 8:5. Since 8 units of time = 12 days, 5 units of time = (12/8) * 5 = 15/2 days.
