Question
5 men and 6 women can do some work in 3 days. If each
man is 100% more efficient than a woman, then find the time taken by 12 men to finish the same work together.Solution
Let the efficiency of each woman be 'x' units/day. So, efficiency of each man = 2x units/day So, total work = 3 × {(5 × 2x) + (6 × x)} = '48x' units So, required time = 48x ÷ (12 × 2x) = 2 days
