P can do a work in 12 days. Q can do the same work in 8 days and R can do the same in 6 days. Q and R start the work and leave after 2 days. P finishes the remaining work in X days. What is the value of 1.1X?
5 days let work be W Speeds P=W/12, Q=W/8 and R=W/6 Since Q and R work for two days work accomplished = 2*(W/8+W/6). Work remaining =5W/12. Time required by P =(5W/12)/W/12=5 days
P can do a work in 20 days. Q can do the same work in 12 days and R can do the same in 16 days. Q and R start the work and leave after 6 days. P finishes the remaining work in X days. What is the value of X?
P can do a work in 19 days. Q can do the same work in 9.5 days and R can do the same in 28.5 days. Q and R start the work and leave after 3 days. P finishes the remaining work in X days. What is the value of X?
X and Y can do a piece of work in 20 days and 12 days respectively. X started the work alone and then after 4 days Y joined him till the completion of the work. How long did the work last?
P is able to do a piece of work in 15 days and Q can do the same work in 10 days. If they can work together for 2 days, what is the fraction of work left?
If 6 men and 8 women can do a piece of work in 10 days and 4 men and 7 women can do it in 12 days, how many days will 4 men and 12 women take to do half of work?
