Question

the selling price of 12 pens equal the cost price of 15. Find the gain percent​

Answer 1

Answer:

25%

Step-by-step explanation:

CP of 12 pens=Rs.12

SP of 12 pens=CP of 15 pens=Rs.15

now,gain=SP-CP=Rs.(15-12)=Rs.3

gain%=gain/cp*100

        =(3/12*100)%=25%

Hence,the gain=25%.

Answer 2

Answer:

25%

Step-by-step explanation:

Here in this case

we put SP as 15

and CP as 12.

So profit = 3.

profit %= 3/12*100= 25%
