An old man has Rs. (1! + 2! + 3! + ... + 50!), all of which he wants to divide equally (without fractions) among his n children. Then, n may be

• ans is 3
  there are three children for a old man
  1!+2!=3 so these Rs.3 can be divided 1 for each one

  for example 4!=24,Rs.8 for each
  and so on...
  so there three children for old man
