Anjali and Manju together can do a piece of work in 5 days. If Anjali does twice as much work as Manju in a given time, how long would Anjali alone take to do the work?
7.5 days
Let Manju's work rate be x units/day. Anjali's work rate = 2x units/day. Together, they complete the work in 5 days, so their combined work rate is (x + 2x) = 3x units/day. Total work = 3x * 5 = 15x units. Time taken by Anjali alone = Total work / Anjali's work rate = 15x / 2x = 7.5 days.
