Question

the cost price of 16 notebooks is equal to the selling price of 12 notevooks .find gain percent

Answer 1

cp=16
sp=12
gain=16-12=₹4
gain%= 4/16 × 100
answer=25%

Answer 2

Let the cost price of single notebook be x.

Given that Cost price of 16 notebooks = SP of 12 notebooks.

SP of 12 notebooks = 16x.

SP of 1 notebook = 16x/12 = 4x/3

We know that Gain = SP - CP
 
                                =  4x/3 - x

                               = x/3.


Gain% = Gain/CP * 100

           = x/3/x * 100

           = 33.33% (or) 33 1/3%


Hope this helps!
