Question 1:
A and B can together complete a piece of work in 4 days. If A alone can complete the same work in 12 days, in how many days can B alone complete that work ?
A.4 days
B.5 days
C.6 days
Feedback(A+B)'s 1 day work = 1/4 A's 1 day work = 1/12 B's 1 day work = 1/4−1/12)= 3−1/12=1/6 So B alone can complete the work in 6 days
D.7 days
