YOUR ANSWER WILL MARK AS BRAINLIST.​

Answer 1

Answer:

Let the cost price of each one be ₹x and the selling price of each pen is y.

Cost price of 15 pen = 15 × x = 15x

Selling price of 20 pen = 20 × y = 20y

As per statement :

15x = 20y

y = 15x/20

y = 3/4×

y = 0.75x

Loss percentage = (Cost price - sale price)/Cost price ×100

Loss % = (x - 0.75x)/x ×100

Loss % = 0.25x/x × 100

Loss % = 0.25 × 100

Loss % = 25%
