Answers
Given : a man complete 7/8 of a job in 21 days.
quantum of work is further increase by 50 %
To Find : how many more days will it take him to finish the job
Solution:
Let say work to be done = 8W
Man completed (7/8)8W = 7W in 21 Days
=> W is done in 3 Days
quantum of work is further increase by 50 %
Hence total work = 8W + (50/100)8W = 12W
Work remaining = 12W - 7W = 5W
W is done in 3 Days
=> 5W is done in 5 * 3 = 15 Days
Hence 15 more days will it take him to finish the job if quantum of work is further increase by 50 %
