. 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 tables will be left out without at least 1 person?
a) 8 b) 6 c) 2 d) 7

• same number of people can not be seated....
  no. of tables=10
  no. of chairs=4
  1st table= 1 person
  2nd table= 2 person
  3rd table= 3 person
  4th table= 4 person
  5,6,7,8,9,10 table s not occupied by any one....
  so table left without any person= 10-4=6

• The total no. of people has not been given in the question...for eg. if 10 ppl were to b seated, den it cud hav been done lyk: 1+2+3+$..and hence the ans 6..
  Here only the number of tables and chairs around them has been given..

• only 6 will be remaining.
  suppose-
  in 1st tbl 1 prsn is sitting
  then in 1st tbl 1 prsn is sitting
  then in 2nd tbl 2 prsn r sitting
  then in 3rd tbl 3 prsn r sitting
  then in 4th tbl 4 prsn r sitting
  
  further r not possible so 10-4=6

• In each table there are different number of peoples seated so from starting 1 next 2 next 3 next 4 and we will end because only 4 chairs per table so total 4 tables was used so at last 10-4 so the answer is 6
