A tradesman gives 4% discount on the marked price and gives 1 article free for buying every 15 articles and thus gains 35%. The marked price is increased above the cost price by.

• let the printed price is 100.
  he is selling 16 piece in average price of (96*15)/16=90.
  
  so cost price is:(100*90)/135=200/3.
  so in increased 100-(200/3)=100/3
  so he increased 50%

• Let MP be Rs 100
  Hence after 4% discount, SP becomes Rs 96
  Total SP for 15 articles = 96 * 15
  =1440
  ATQ, gains is 35%, so we can find CP for 16 articles (1 is free with 15 ) = (100/135)*1440
  =1066.66
  CP for 1 article then = 1066.66/16
  = 66.66
  So MP is increased above Cost Price = MP for 1 article - CP for 1 article
  = 100 - 66.66
  = Rs 33.34

• After Dis sp=sp-4%sp=96%sp
  Profit=(sp-cp)/cp×100=36
  sell 16 artical = 15sp
  Total = 15sp+96%sp =211%sp
  36%cp+cp=136 %
  Sp = 136/211 =68/105 = 64%
