Answer 1

Lets consider this question -->  Find the sp when cp is rs 80 and gain is 20%

Given that,

Cost price = Rs 80

Gain = 20 %

To find: Selling price

The formula used is:

SP = 100 + profit % / 100 * CP

Substituting the values in formula,  

SP = 100 + 20 / 100 * 80

     =  120 / 100 * 80

    SP = 96

Thus selling price is Rs 96
