Answer 1

Given:

Person sold a radio at 10% profit then he gets rupees 714.

To Find:

What is cost price of radio?

Solution:

Let cost price of radio = C.P

Percentage of profit = X = 10 %

Selling price of radio = S.P = 714

We know the relation between C.P and S.P:

$\mathbf{S.P = C.P \times \left ( 1+\dfrac{X}{100} \right )}$

$\mathbf{714 = C.P \times \left ( 1+\dfrac{10}{100} \right )}$

$\mathbf{714 = C.P \times \dfrac{110}{100}}$

$\mathbf{714 = C.P \times \dfrac{11}{10}}$

$\mathbf{ C.P= \dfrac{714\times 10}{11}}$

On simplify above:

C.P = 649.09 Rupees

Means cost price of radio is 649.09 rupees.
