A can do a certain work in 12 days. B is 60% more efficient than A. How Many days does B alone take to do the same job?
Solution : A does 1/12 part of work in one day.
B would do (1.6 x 1/12) or 0.1333 part of work in one day.
B will take (1/0.1333) or 7.5 days to complete the work alone.
Problem :( :( = Where this 1.6 came from and how??????????????????
