In the reading room of a library, there are 10 tables, 4 chairs per table. In each table there are different numbers of people seated. How many ways they will sit in the library so that no chair would be blank?

• question is wrong.if people will seat in different number on each table then there are only 4 table on which people seat differently.they will seat like 1 man at 1st table,2 person at second,3 person at 3rd table,4 person on 4th table.so rest 6 table will be blank.

• first table =1
  second table=2
  third table=3
  fourth table=4
  since only 4 person can sit on a table hence no other arrangement is done
  so total no of table occupied is 4
  no of table left unoccupied is (10-4)=6
  ans =6

• since there is no way to fill all the chairs, answer is 0
  
  i.e there are 0 possible ways.

• 10 tables, each with 4 chairs Each table has a different number of persons sitting....This is not possible as there are only 4 chairs.. The different combinations can be 0, 1, 2, 3 and 4...the sixth table would have one of the above combinations..Thus the rule is violated..
  Plus, if different numbers of people occupy a table, there would be blank spaces...so how can we calculate the possibilities of the library being fulling occupied.. This is an ambiguous question

• 1st table=1
  2nd table=2
  3rd table=3
  since only 4 chairs per table, 4 members are maximum to be seated and these people can be seated in reamaining tables(10-3)
  answer is 7
