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
