Question

if the selling price of 20 pens is the same as the cost price of 24 pens then gain or loss percent is​

Answer 1

Answer:

If the cost price of 24 pens is equal to the selling price of 20 pens,

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

Cost price of 24 pen = 24 × x = 24x

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

As per statement :

24x = 20y

y = 24x/20

y = 6/5×

y = 1.2x

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

Loss % = (x - 1.2x)/x ×100

Loss % = 0.25x/x × 100

Loss % = 0.25 × 100

Loss % = 25%

Answer the percentage loss is 25 percent
