1. (selling price-buying price)/buyingprice=profit ===> (selling price/buyingprice)-1=profit===> (selling price/buyingprice)=profit+1

   (2selling price-buying price)/buyingprice=3profit ==>2(profit+1)-1=3profit ===> profit=1 or 100%

2. suppose buying price is 1/- then selling price make 2/-
   if selling price is doubled then SP = 4/-
   buying Price is = 1/-
   profit is = 4-1 = 3/-
   so profit percentage is (3/1)*100=300%
