Question

find the CP= ? SP=123 Profit=21​

Answer 1

Given: $SP=123Rs. \ and\ Profit=21Rs.$

We have to find the value of the cost price.

As we know that the formula is used to calculate the profit is:

$Profit=SP-CP$

By using the above concept, we are finding the value of the cost price.

We are solving in the following way:

We have,

$SP=123Rs. \ and\ Profit=21Rs.$

So,

$Profit=SP-CP$

Putting the given values in the above formula we get,

$=>21=123-CP\\=>21-123=-CP\\=>-102=-CP\\=>CP=102$

Hence, we get the value of the cost price is$102$.
