1. If x flowers costs y$, and x+10 flowers will be given for only 2$, then what is the value of x & y such that a customer gets a 80 cents profit on 12 flowers.

• 1$=100 cents
  12 flowers=80 cents
  go by options ans is (5,1)
  5 flowers-100 cents
  12 flowers-240 cents
  (5+10=15 flowers)=200
  12 flowers=160
  so,savings is 80rs

• if we consider x=2
  than y should be y=0.4667.
  Because,
  Actual price of dozen roses is 2.80 dollars.
  so for x=1 rose she will have to pay y=0.233
  
  Same way for x=2,y=0.4667

• 1$=100 cents
  12 flowers=80cents
  6 flowers =40 cents
  3 flowers =20 cents
  therefore (12+3=15) flowers =(80+20=100)cents
  ie. 15 flowers =100 cents
  1 flower =100/15=20/3............(a)
  30 flowers=200 cents...................(1)
  given x+10 flowers will be given for only 2$
  ie. x+10 flowers=200 cents................(2)
  comparing eq (1)and eq(2)
  x+10=30
  x=20 flowers
  
  required cent=20*20/3=400/3
  hence x=20 and y=400/3
