Question
15 men working 9 hours daily can finish a task in 36
days, while 18 women working 6 hours a day complete the same task in 72 days. How many days will 6 men and 3 women working 9 hours a day take to finish the job?Solution
ATQ,
Let the efficiency of a man and a woman be 'M' and 'W' units/day respectively. 15 × 9 × 36 × M = 18 × 6 × 72 × W Or, M : W = 2 : 1 Let M = 2e and W = e Total work = 15 × 9 × 36 × 2e = 9720e units Required time = 9720e ÷ [(6 × 2e + 3 × e) × 9] = 9720e ÷ 135e = 72 days
