A box of 150 packets consists of 1kg packets and 2kg packets. Total weight of box is 264kg. How many 2kg packets are there?
(a) 100 (b) 114 (c) 200 (d) 208

• let 1kg packet x number and 2 kg packet (150-x)so
  x+2(150-x)=264
  -x=-36 so x=36 then 2 kg packet=(150-36)=114(ans)

• 114.
  
  A box of 150 packets consists of 1kg packets and 2kg packets. Total weight of box is 264kg.
  
  If all boxes are of 1 kg, wt will be 150 kg.
  
  Diff = 264-150 =114.
  
  so 114 boxes have wt of 2 kg instead of 1 kg.

• 2kg packets are 114..114*2=228+(36*1kg packet)=264 which is the weight of the box.

• x = number of 1 kg packets , y = number of 2 kg packets
  x+y = 150
  x+2y=264 ; y=114 & x = 36

• let 2 kg packets be x. 2x+(150-x)=264
  
  
  
  
  
  
  let no. of 2 kg packets be x.
  then 2 *x+(150-x)=264 =>x=114
  so ans is (b)
