Question
A tradesman gives a 4% discount on the marked price and
gives an article free for buying every 15 articles and thus gains 35%. Find out by what percentage the market price is above the cost price.Solution
Let CP = 100. MP = x. SP after 4% discount: SP =0.96x Effective SP per article (16 articles, 1 free)- Effective SP = (15x -0.96x)/ 16 = 0.9x Given a 35% gain 0.9x=135 x=150 Percentage above CP= (150 -100) /100 x 100 =50%
