( Complete question)
Given:
One hundred men in 10 days do one-third of a piece of work.
To find:
Men must be discharged at the end of the 18th day so that the remaining work will complete in the estimated time.
Solution:
1) If the 100 men do the work for 10 days then the 160 men complete the remaining work in M days which is given by:
- 100×10/1 = 160×M/2 ( By MDH rule)
- M = 25/2
- M = 12.5 Days.
2) After the 18 days, the number of men required Y to complete the remaining work on time,
The number of the days left is 5 days as per estimated and 4.5 as calculated.
- 160×4.5 = Y×5
- Y = 144
The men discharge to complete the work on time is 160-144 = 16 Men.
16 Men were discharged after 18 days.

One hundred men in 10 days do one third of a piece of work.
100 men work in 10 Days = 100 * 10 = 1000 man days
It is 1/3 of Work
Hence total work = 3000 man days
Remaining work = 3000 - 1000 = 2000 man days
To be completed in 13 more days total 23 Days
from 11th to 18th - 8 days
Men = 100 + 60 = 160 Days
Work done = 160 * 8 = 1280 Man days
Work Left = 2000 - 1280 = 720 Man Days
Days left = 13 - 8 = 5 or (23 - 18 = 5)
Men required = 720/5 = 144
Men to be discharged = 160 - 144 = 16
16 Men to be discharged at the end of 18th day
