Some people are standing square. From them 32 are removed and
then form a small square and then 8 more removed. now we cannot
form the square. so how many people are there at the beginning?

• ans is 81
  
  initial 81 form square and removing 32 gives 49(7*7) which also give square.
  romoving 8 results in 41 which is not perfect square
