Question

A shopkeeper marks up his goods by 40% and gives a discount of 10%. Apart from this, he uses a faulty balance also, which reads 1000 gm for 800 gm. What is his net profit percentage?
A)57.5%
B)63.5%
C)42.5%
D)36.5%

Answer 1

Since he sells the goods at a discount the selling price will be (40% - 10%) = 30% profit.

The profit is 30%.

Lets take the buying price as x.

The profit on the 1000g rather 1 kg will be 30% of x.

This gives us 0.3x

In reality this is the profit for 800 g.

The profit he gets for 1000g will be :

1000/800 × 0.3x = 0.375x

To change this to percentage it becomes :

0.375x/x × 100% =37.5

The overall percentage profit gained by the seller will be given as : 37.5%

Answer 2

Answer:

Step-by-step explanation:

Let us assume his CP/1000 g = `100

So, his SP/kg (800 g) = `126

So, his CP/800 g = `80

So, profi t = `46

So, profi t percentage = 46/80 × 100 = 57.5%
