Question

A tradesman gives 4% discount on the marked price and gives an article free for buying every 15 article and thus gains 35% .the marked price is approximately how much percentage above the cost price

Answer 1

Answer:50%

Step-by-step explanation:MP is Rs.X

S.P of 16 articles = 15X - 4% of 15X = 15X - 15X/25 =72X/5

S.P of one article = 9X/10

Gain = 35%

C.P = (9X/10x100)/(100+35) = 90X/135..

The marked price is raised by 50% above the C.P.

Answer 2

Answer:

Hope it helps

Step-by-step explanation:Let the Cost Price of each article be ₹100.

    Then C.P of 16 articles will be ₹100 x 16 = ₹1600.

    The tradesman earns 35% profit.

    So, S.P of 15 articles = 135/100  ×1600 = ₹2160

    Now, S.P of 1 article = 2160/15 = ₹144

    If S.P is 96 then marked price is ₹100.

    If S.P is 144 then marked price is 100/96  ×144 = ₹150

    Therefore, marked price is 50% above than Cost Price.
