A certain number of men can finish a piece of work
in 100 days. If however there were l0 men less, it
would take another 10 days to finish the work. How
many men were there originally?
(1) 50 (2) 75 (3) 82
(4) 110 (5) None of these

• (4).
  let M is the no of original man then according to question M*100=(M-10)*110
  =>M=110.

• If 'm' men worked for ’d’ days to finish a job, then we can say 'm*d' are required to finish the job.
  here let m=m, d=100
  since 10 me less, we can write (m-10)*110
  ie.. m*100 = (m-10)*110
  therefore m=110

• Work rate*time=work done
  So consider option 4. 110
  110*100=11000 men days
  if 10 men less it would take another 10 days ie
  100*110=11000 men days
  so option 4. is correct
