what is the discount shop keeper give on buy 6 get 1

• 
  let CP of each item is 100 rs then
  CP of 6+1= 7 items = 7*100 = 700 rs ,
  but on buy 6 get 1 offer, we have to pay for 6 items i.e 6*100 = 600 rs
  
  %discount = (700-600)/700 *100 = 100/7 = 14 2/7 % = 14.28 %

• let cost of single item be x
  then cost of 7 such items be 7x
  we pay for 6 only i.e. 6x
  hence discount offered {(7x-6x)/7x}*100
  = (1/7)*100 = 14.28%
