Question

How much percent more than the cost price should a trader marks his goods so that after allowing a discount of 20% on the MP he still makes a profit of 40%

Answer 1

Answer:

50%

Step-by-step explanation:

here if,cp=100%

since he gets 20%

he should trade by 120

after giving discount it is x

x-20/100*x=120

100x-20x =120*100

80x=12000

x=12000/80

x=150

: it's 50%
