Answer 2

Answer:

The cost price of per microvave is 5000 rupees.

Step-by-step explanation:

Given,a showroom offers a 10% discount on a microwave ,whose marked price is rs.8000.

So, amount of discount

$= 8000 \times \frac{10}{100} \\ = 80 \times 10 \\ = 800 \: rupees$

Again the show room gives a blender worth rs.1200 as a complimentary gift with the microwave.

Therefore final selling price is

$8000 - (800 + 1200) \\ = 8000 - 2000 \\ = 6000 \: rupees$

Now it is also given they gain profit 20%.

Let cost price be x.

So, selling price

$x \times \frac{120}{100} \\ = x \times \frac{12}{10} \\ = x \times \frac{6}{5} \\ = \frac{6x}{5} \: rupees$

Here $\frac{6x}{5}$ rupees and 6000 rupees both are selling price of the microwave.

So,

$\frac{6x}{5} = 6000$

By cross multiplication,

$6x = 6000 \times 5 \\ 6x = 30000 \\ x = \frac{30000}{6} \\ x = 5000$

Therefore cost price of the microwave is 5000 rupees.

This is a problem of percentage.
