• How many three digit positive integer, with digit x,y and z in the hundred,tens and units place respectively, exist such that x 2*3= 6 possibilities
  IF y=4 ,x=1,2,3 & z=0,1,2,3 => 3*4= 12 possibilities
  IF y=5 ,x=1,2,3,4 & z=0,1,2,3,4 => 4*5= 20 possibilities
  .......
  If y=9 , x=1,2,3,4,5,6,7,8 & z=0,1,2,3,4,5,6,7,8 => 8*9= 72 possibilities
  
  Adding all possibilities 240 is ans
