Question

can anyone answer this question quickly please with proper explanation

Answer 1

Let the CP be Rs a

SP = 6/5 * a

SP = 6a/5

Gain = SP - CP

= 6a/5 - a

= a/5


Gain % = Gain * 100 / Cp

= (a/5) * 100 / a

= 100 / 5

= 20%

Answer 2

Let the cost price of the laptop be x.

Then the selling price of the laptop = 6x/5.

We know that Profit = Selling price - Cost price

                                  = 6x/5 - x

                                  = 6x - 5x/5

                                  = x/5.


We know that Profit % = Profit/CP * 100

                                      = x/5/x * 100

                                      = 100/5

                                      = 20.


Therefore the profit % = 20%.



Hope this helps!
