Question
X and Y can complete a work in 12 days and 10 days
respectively. With the help of Z, X and Y together can complete the work in 5 days for a total salary of Rs 6000. So how much should 2 get paid for his share of the work?Solution
- Work done by X in 1 day =1/12 Work done by Y in 1 day =1/10 1 Work done by (X+Y) in 1 day=1/12+ 1/10 =11/60  Work done by (X+Y) in 5 days =11/60) ×5=11/12  Work left = 1-11/12=1/12 Hence, work done by Z in 5 days = 1/12  Hence, share of 2 in total salary 6000 = 6000x1/12 = 500.
