if there is a different kind of burger in that some 1st 5th 9th... so on contain mushroom and 2nd 9th 16th ...and so on contain chilies. while 1st 5th 9th...contain chilly ... while other burgers contain butter ....if there is the machine which produces 660 burgers then find the number of burgers which contain butter...

• 154..bcoz mushroom,chilly contain 198
  And chillies contain 110
  So 660-(198+198+110) = 154

• for chilly and mushroom it is same kind to be pasted so there is no chance of burger
  from 1 to 660(1,5,7....657)---165 counts
  for chillies(2,9,16,...660)---96(which includes the same layer of chilly and mushroom in chilles)
  need to subtract the chilly and mushroom layers from chillies
  total no of chillies layers as same in mushroom and chilly=21
  so the total number of chilies=96-21=75
  total no of layers the paste applied=75+165=240
  no of butter layers=660-240=420

• number of mushroom=> a1+(n1-1)d=657 (calculation =>660+reminder(660/4)+a1-d1..eg here we know a1=1,d1=4. if a1=0 the series exactly reach 660. But a1=1 So it reach 661. But 661 not in range. We must reduce 4 from outcome Thus 657 is the last occurrence for mushroom.
  n1=mushroom=165
  similarly a2+(n2-1)d=660 (658 divisible by 7 and a=2 thus reaches 660)
  n2=chilly=95
  SO butter mixed =660-n1+n2=660-260=400
  So the number of burgers containing butter is 400
