in a reading room of library , there are 10 tables and each table has 4 chairs.at each table , there are different no of people seated . how many tables are left out without atleast one person?

• since there are different no of people seated at every table , so at most 4 tables can be filled with the person count on each table being 1,2,3,4 respectively..
  so, 6 tables would be left out without at least 1 person..

• answer is 6
  
  there are 4 chairs on each table so maximum possible people on one table are 4
  
  and on each different number of people are there.!
  
  so 1 on 1 table
  then 2 on 2nd one
  then 3 on 3rd one
  then 4 on 4th one
  so left tables are 10 - 4 = 6
