12 women can complete a piece of work in 90 days. They worked together and after 30 days, 2 women left the work. How many more days will women take to complete the remaining work?

72 days

12 women can do the work in = 90 days

Total work = (12 × 90)

Work done by 12 women in 30 days = (12 × 30)

Remaining work =  (12 × 90) - (12 × 30) = (12 × 60)

Remaining work to be done by = 12 -2 = 10 women

Work will be done in = \(\frac{12 × 60}{10}\) = 72 days
