7 x 12 men complete the work in 1 day\nTherefore, 1 man’s 1 day’s work = 1/84\n7 men’s 5 days work = 5/12\nRemaining work = 1- 5/12 = 7/12\n5 men’s 1 day’s work = 5/84\n5/84 work is don by them in 1 day\n7/12 work is done by them in ((84/5) x (7/12)) = 49/5 days = 9 4/5 days
Therefore, the answer is (E).
