Question

A man allows 20 % discount on the M.P. of his goods and still earned a profit of 4 % . What is the cost price of the goods for him , marked at rs 600

Answer 1

80% of 600=480

CP=480*100/104

Answer 2

d%=20%

p%=4%

mp=rs 600

discounted price= d% of mp

                            = 20/100*600

                               =rs 120

sp= mp-discount

     = 600-120

     =rs 480

the sp=cp

because it is the sp of the shopkeeper but cp of the customer .

so cp=rs 480
