Question

if 35 womens do a piece of work in 12 days how many womens are to be requires to do same work in 21 days

Answer 1

in 12 days number of women required to complete the work is 35.

so, in 1day number of women required to complete the work will be 35×12

and in 21 days number of women required will be 35×12/21=20

therefore 20 women will be required to complete that piece of work in 21days.
