1. A project requires 12 women to complete it in 16 days. 12 women started working and after a few days from the start of the project, 4 women left. If the remaining project was completed in 18 days, in how many days the whole project was completed?

Let the work done by 8 women in 18 days = $$W_2$$ => $$frac{M_1 imes D_1}{W_1} = frac{M_2 imes D_2}{W_2}$$ => $$frac{12 imes 16}{1} = frac{8 imes 18}{W_2}$$ => $$W_2 = frac{18}{12 imes 2} = frac{3}{4}$$ Thus, remaining work = $$1 - frac{3}{4} = frac{1}{4}$$ This part of work was done by 12 women. $$ herefore$$ Time taken by them = 4 days => Required time = 18 + 4 = 22 days
