If 10 men or 18 women can do a work in 45 days then how many days would it take 25 men and 15 women to do twice the work?

Question: If 10 men or 18 women can do a work in 45 days then how many days would it take 25 men and 15 women to do twice the work?Solution:Here,10 men = 18 women∴ 1 men = 18/10 women∴ 25 men = (18 × 25)/10 women= 45 women∴ 25 men and 15 women = (45 + 15) = 60 womenATQ,18 women can do the work in 45 days∴ 1 women can do the work in 45×18 days∴ 60 women can do the work in (45 × 18)/60 days= 27/2 daysHence to do twice the work time need = (27/2) × 2 days= 27 days
