Question
18 men, working 8 hours a day, can complete a task in 21
days. If a woman is 33(1/3)% less efficient than a man, how much time will it take for 24 women, working 6 hours a day, to complete the same task?Solution
Let the efficiency of a man be '3e' units/day. Efficiency of a woman = (2/3) X 3e = '2e' units/day Let the required time be 'T' days. So, 18 X 8 X 21 X 3e = 24 X 6 X T X 2e Or, 'T' = (63/2) = 31.5
