Percentage is a ratio, expressed as parts per hundred.
You can consider it a fraction, or a decimal.
If the selling price is x,
and the cost is 25% of x, it means the cost is 25/100=0.25=1/4 of x, or 0.25x.
So, in absolute terms, the profit is
selling price-cost=x-0.25x=0.75x .
As a ratio/fraction/percentage of the cost, that is
0.75x/0.25x=3=300/100=300% .
For an item selling at price=100, the merchant paid cost=25,
and made a profit of 75,
which is 3 times the cost,
or 300% of the cost,
If the cost price of an item is 25% of its selling price , what is the % of profit ?
