a tradesman gives 4% discount on the marked price and gives 1 article free for buying every 15 articles and thus gain 35%. The marked price is increased above the cost price by?
Hi
Let the price of 16 articles be 100 rupees
Gain=35%
Selling price of 15 articles be = 100 x 100+35/100=Rs.135
Marked price of 15 articles x (100-4)/100=rs.135
Marked price of 15 articles= 135 x 100/(100-4)= 140.625
Cost price of 15 articles = 100 x 15/16 = 93.75
Required increment = (140.625 - 93.75) x 100/93.75 = 50%
Marked price is 50% more than the cost price.
Hope this information is helpful.
