Answers
Answer:
140 men ll finish d work in 80 days
140 men's 1 day work = 1/80
1 men's 1 day 1 work = 1/140 * 80 = 1/11200
After 50 days , part of work finished is
50 * 1/80 = 5/8
Remaining work = 1 - 5/8 = 3/8
150 men's 1 day work 150 * 1/11200 = 3/224
Remaining work can be completed in
3/8 * 224/3 = 28 days
[Since already 50 days over, + 28 days = 78 days... But before it was completed in 80 days ... so 80 - 78 = 2 days]
so d work ll be completed before 2 days
140 men ll finish d work in 80 days
