Answer 2

Answer:-

The Cost price of the radio is Rs. 1800.

Explanation:-

Given :

Selling price of a radio= Rs. 1980

Gain percentage= 10%

To find :

Cost price of the radio

Solution :

Let the C.P of the radio be x

As we know that,

$s.p = c.p(1 + p\%)$

$= > 1980 = x(1 + 10\%)$

$= > 1980 = x(1 + \dfrac{10}{100})$

$= > 1980 = x( \dfrac{10 + 100}{100} )$

$= > 1980 = \dfrac{110x}{100}$

$= > x = \dfrac{1980 \times 100}{110}$

$= > x = 1800$

Hence, The C.P is Rs. 1800
