Question
5 men and 10 women can do some work in 3 days. If each
man is 150% 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 × 2.5 = '5x' units/day So, total work = 3 × {(5x × 5) + (10 × 2x)} = '135x' units So, required time = 135x ÷ (9 × 5x) = 3 days
