Answer 2

Answer:

Required selling price is 8640 rupees and profit percent is 8%.

Step-by-step explanation:

Given,a dealer marks a refrigerator 20% above the cost price of ₹8000.

Therefore, cost price = 8000 rupees.

and marked price = 20% above 8000 rupees

$= \frac{100 + 20}{100} \times 8000 \\ = \frac{120}{100} \times 8000 \\ = 120 \times 80 \\ = 9600 \: rupees$

It is also given the dealer gave 10% discount.

So, selling price = 10% discount on 9600 rupees

$= \frac{100 - 10}{100} \times 9600 \\ = \frac{90}{100} \times 9600 \\ = 90 \times 96 \\ = 8640 \: rupees$

We know cost price means 100%.

So,8000 rupees mean 100%

By Unitary method, 1 rupee mean $\frac{100}{8000} \%$

8640 rupees mean

$\frac{100}{8000} \times 8640 \\ = 108 \%$

Therefore profit

$= (108 - 100)\% = 8\%$
