Question

p and q together can complete a piece of work in 36 days and the efficiency of q is 33(1/3)% Lee's than efficiency of p find in how many days Q alone can complete the whole work​

Answer 1

Answer:

JobA can complete the work alone in 36 days.

B is 33.33% more efficient than A

B can finish the work alone in 27 days.

Both can do 1/36 + 1/27= 7/108 of the work in 2 days.

So when they do on alternate days in 30 days they will do 15(7/108) = 105/108 of the work and 3/108 = 1/36 is still left over. And since A started the work and his capacity is 1/36 of the work, he will finish the remaining work in 1 day.

Hence the total number of days taken by A and B to do the work when they do on alternate days with A starting the work is 30+1 =31 days.
