Question

A shopkeeper marks his goods 30% above the C.P and gives a discount of 10% to the customer. At the time of selling the goods he uses 700 gm weight instead of 1 kg. Find his profit percentage. 673% 33% 20% 6717% ​

Answer 1

Market price = 130 % of 100 = 130

selling price = 130-15% of 130 = 110.5

Net profit = 110.5 - 100 = 10.5 Rs on Rs 100

Net percentage gain = 10.5 %

Answer 2

Answer:

Let C.P. of the goods be RsC

Marked price will be =C.P.+30 % of C.P.=

100

130

×C=

100

130

×C=Rs1.3C

Since the shopkeeper gives 10 % discount on the marked price , Selling price =

100

90

×1.3C=Rs1.17C

Now, Gain % =

C.P.

S.P.−C.P.

×100=

C

1.17C−C

×100=17 %
