Question
5 men and 6 women can do some work in 3 days. If each
man is 50% more efficient than a woman, then find the time taken by 9 men to finish the same work together.Solution
Let the efficiency of each woman be '2x' units/day. So, efficiency of each man = 2x × 1.5 = '3x' units/day So, total work = 3 × {(5 × 3x) + (6 × 2x)} = '81x' units So, required time = 81x ÷ (9 × 3x) = 3 days
