Question

Find the SP, when CP = ₹20 and gain = ₹10%

Answer 1

Hello

Here's your answer

Profit % = $\frac{profit}{cost price}$×100
= $\frac{10}{20}$×100
= ₹50

Selling price = cost price + profit
= 20 + 50
= ₹70

Answer 2

selling price = (100+gain%/100)*cost price

                     =110/100*20

                       =rs.(11*2)

                        =Rs.22

hope the above answer is correct!
