Question

Answer 1

Answer:

Gain of 25%

Step-by-step explanation:

Let Selling Price of one book be P

Selling Price of 20 books = 20P

Selling Price of 25 Books = 25P

Now

Cost Price of 25 Books = Selling Price of 20 Books

Cost Price of 25 Books = 20P

while, Selling Price of 25 Books = 25P

Selling Price > Cost Price , it is a gain

Gain = Selling Price - Cost Price

        = 25P - 20P

       = 5P

Gain% = (Gain × 100)/Cost Price

           = (5P × 100)/20P

           = 25%

∴ It was a gain of 25%

Answer 2

HELLO!

Here's the Answer :

☆☆☆☆☆☆☆☆


Let the cost price of each book be x.

Cost price of 20 books = 20x

Selling price of 20 books = Cost price of 25 books = 25x

Thus,
CP = 20x
SP = 25x

Profit =
SP - CP
25x - 20x
5x

Profit % =
P/CP × 100
5x /20x × 100
5/20 × 100
1 /4 ×100
100/ 4
25%

So, the gain percentage is 25 %
