Question

plz answer step by step

Answer 1

15% profit or rs 30 is the answer....

Answer 2

Given that 5 kg of coffee is mixed with 2 kg of chicory.

= > The total cost of the (5 + 2 = 7) mixture = 5 * 250 + 2 * 75

                                                                        = 1400.



= > Then the cost of 1kg mixture = 1400/7

                                                      = 200


= > Given that selling price of the mixture = 230.

Here Selling price > Cost price. 

= > We know that Gain = Selling price - Cost price

                                 = 230 - 200

                                 = 30.



= > We know that Gain% = (Gain * 100)/CP

                                    = (30 * 100)/200

                                    = 15%.


 Therefore the Gain % of the mixture = 15%.


Hope this helps!
