Given: 12 women can weave 132 m of cloth Work to be done = 187 m of cloth Formula used: Efficiency of per person = Total work/Number of persons Calculation: Efficiency of 1 woman = 132/12 m = 11 m of cloth Now, Total cloth to be waived = 187 m Number of women needed = 187/11 = 17 women ∴ The number of women needed to weave 187 m of cloth is 17
