Nyc question !!

CP OF 24 BOOKS =24RS
SP OF 30 BOOKS =30RS

Answer 2

$\huge\textbf\green{Answer:-}$

Let x be the cost price for 1 book

So, therefore the Cost price of 24 book = 24y

And, the cost price of 30 book = 30 y

Selling price of 24 book= 30y

Profit= Selling price - Cost price

$= (30y - 24y= 6y)$

$Profit = \frac{6y}{24y} × 100$

Therefore, gain = 25%(profit)
