RRB Group-D Model Paper 19 with answers for online practice

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
