If the cost price of 15 pens is equal to the selling price of 20 pens, find the gain or loss per cent

Answers

Answered by apekshanegi40

20

Step by step explanation:

Let the CP of each pen be ₹ 1

CP of 20 pens = ₹20

SP of 20 pens = CP of 15 pens = ₹15

Thus, CP= ₹20 and SP = ₹15

☞loss= (CP) -- (SP) = ₹(20--15) = ₹5

☞loss% = (loss/CP × 100)%

= (5/20×100)% = 25%

Hence, loss% = 25%
