Question

if selling price of 5 pen is equal to the cost price of 4 pen.then, find the gain or loss percent​

Answer 1

Answer:

Hi

Step-by-step explanation:

Selling price of pen(sp)=Cost price of pen(cp)

Let cost price(cp) of 4pens=4Rs

cost price(cp) of 5pens=5Rs

Selling price(sp) of 5pens=4Rs

Loss=Cost price(cp)-Selling price(sp)

Loss=5Rs-4Rs

Loss=1Rs

Loss percentage(%)=Loss×100/Cost price(cp)

Loss percentage(%)=1×100/5

Loss percentage(%)=100/5

Loss percentage(%)=20%
