A book seller allowed 10% discount on printed price. He gets 30% commission from publisher. His profit in percent will be?

120%
228⁴/₇%
325%
428³/₇%

Answer:- 4

Explanation:-

Solution:

Let the marked price be of book be Rs. 100
Cost price of the retailer = Rs. (100 - 30) = Rs. 70
Selling price for the retailer = Rs. 90
∴ Profit percent

= (90 - 70 70) \times 100 = (20 70) \times 100 = 200 7 = 28 4 7 %

$\eqalign{ & = \left( {\frac{{90 - 70}}{{70}}} \right) \times 100 \cr & = \left( {\frac{{20}}{{70}}} \right) \times 100 \cr & = \frac{{200}}{7} \cr & = 28\frac{4}{7}\% \cr}$
