Answer»

A can complete the work in 12 DAYS working 8 hours a day

=> Number of hours A can complete the work = 12×8 = 96 hours

=> Work done by A in 1 hour = 1/96

B can complete the work in 8 days working 10 hours a day

=> Number of hours B can complete the work = 8×10 = 80 hours

=> Work done by B in 1 hour = 1/80

Work done by A and B in 1 hour = 1/96 + 1/80 = 11/480

=> A and B can complete the work in 480/11 hours

A and B WORKS 8 hours a day

Hence total days to complete the work with A and B working TOGETHER

= (480/11)/ (8) = 60/11 days = 5 5/11 days

A can complete the work in 12 days working 8 hours a day
