Question

Q6. P can complete a work in 12 days working 8 hours a day. Q can complete the same work in 8 days working 10 hours a day. If both P and Q work together, working 8 hours a day, in how may days they can complete the whole work?

​

Answer 1

Step-by-step explanation:

M1×W1= M2×W2

P×12×8=Q×8×10

96P=80Q

6P=5Q

P/Q= 5/6

P+Q= (5+6)=11

NOW

M1×W1= M2×W2

P×12×8= (P+Q)×8×X

5×12×8=11×8×X

60=11X

60/11=X

5 5/11=X
