# Q1. The cost price of 15 bananas is equal to the selling price of 12. Find the profit or loss percent.

Cost price of 15 bananas = Selling price of 12 bananas

Now, we know

Selling price = Cost price + Profit

Cost price of 15 bananas = Cost price of 12 bananas + Profit on 12 bananas

$\Rightarrow $ Cost price of 15 bananas - Cost price of 12 bananas = Profit on 12 bananas

$\Rightarrow $ Profit on 12 bananas = Cost price of 15 bananas - Cost price of 12 bananas

$\Rightarrow $ Profit on 12 bananas = Cost price of 3 bananas

Profit percentage =

__CP__of 3

__bananas__× 100

CP of 12 bananas

Profit % =

__3__× 100 = 25%

12
