Question

the cost price of 15 bottles is equal to the selling price of 12 bottles find the profit and loss percentage explain me clearly

Answer 1

Let the Cost Price of 1 bottle = 1 rupee

Cost Price of 15 bottles = 15

Selling Price of 12 bottles = 12

Loss = 15 - 12 = 3

Loss % = (3/15) * 100

            = 20%.

Answer 2

Cost price if 15 bottle = selling price of 12 bottle,
So, clearly it have profit...

Now,
Cost price of 1 bottle= x/15
Selling price of 1 bottle=x/12

Profit = X/12-X/15 = X/60

So,
Profit % = (profit/cost price)×100
= [(X/60)/(X/15)]×100
= 25%

Final Answer = 25%......
