# Problem22: Find the profit percent or loss percent of the following data CP rupees 400 and SP is equal to rupees 500​.

Solution:

This is clear that here is profit because sale price(SP) is greater than cost price (CP).

Formula for profit is given by;

$Profit=SP-CP$

So,

$Profit= 500-400=100$

Now come to the ppoint asked i-e what this profit is percent?

Remember that percent is always taken with repect to the cost price!

So, let 100 = x % of CP

Mathematically,

$100=\frac{x}{100}\times CP$

$100=\frac{x}{100}\times 400$

Hence,

$x=25$

Profit is 25% of the CP
