18 workers can complete the construction of a wall in 36 days how many more days will 12 workers take to complete the same wall?
[A] 18
[C] 15
[B] 13
[D] 12

• 18 workers can construct in 36 days
  1 worker can construct in 36*18 days
  12 worker can construct in 36*18/12 days=54 days
  extra days=54-36=18 days

• 18 workers completes a wall in 36 days
  12 workers will take 12*36/18=24 days
  Hence 12 workers will take 36-24=12 more days to complete the same wall.
  Ans-12 days

• 18 workers take 36 days to construct the wall
  1 worker takes 1/(36*18)days
  while 12 workers take 12/(36*18) days to construct same wall
  i.e... 48 days
  therefore more days needed are 48-36= 12 days

• (18*36) worker can complete a work in one day.
  1 workers 1 day work = 1/18*36
  12 workers take to complete the work=12/18*36 = 54 days
  extra day=54-36=18 days.

• 18 mens takes 36 days
  1 man will take 18*36 days [i.e. 18*36=648]
  So, 12 men will take 648/12 days [i.e. 648/12= 54 days]
  Therefore, 54-36 (work by 12men - 18men) = 18 days
