Question

At what rate percent the cost price must be increased to fix the selling price of an article to make 20% profit after allowing 10% discount to the customer?​

Answer 1

Answer:

Let the CP = 100 Rs.

Then, SP = 120 Rs.

Let the marked price = x Rs.

Then, 90% of x = 120 Rs.

$latex => x = \frac{120\times 100}{90}&s=1$

$latex = \frac{400}{3} = 133\frac{1}{3}\%&s=1$

Hence, the marked price is $latex 33\frac{1}{3}\%&s=1$ above the cost price.
