Question

the cost price of 15 bottles is equal to the selling price of 12 bottles . find the profit or loss percent.

Answer 1

Let CP of 1 bottle be ₹ 1 .

CP of 15 bottles = SP of 12 bottles

CP of 12 bottles = ₹ 12

SP of 12 bottles = ₹ 15

SP > CP ( gain )

Gain = SP - CP

= 15 - 12

= ₹ 3

Gain % = gain/CP× 100

= 3/12×100

= 25 %

Answer = 25% profit
