Question

a trader earns 29% profit after allowing the discount of 43% .By how much is his marked price more than that of his cost price​

Answer 1

Step-by-step explanation:

let the MP be Rs 100

SP = 100 - (43×100)/100

SP = Rs 57

now by selling it for Rs 57, he earns 29% profit

therefore SP = CP + 29% profit

57 = CP + 29 CP/100

57 = [100 CP + 29 CP] / 100

5700 = 129 CP

therefore CP = 5700/129

CP = Rs 44.2

MP - CP = 57 - 44.2 => Rs 12.8 Answer
