Answer 1

Step-by-step explanation:

Given A milk vendor mixes water with milk in the ratio 1:4, he then measure 800 ml instead of a litre and sells the milk at a nominal profit of 20% over the cost price what is his actual profit percentage

Let the cost price of pure milk be Rs 10 / litre.

So water = 200 ml

Milk = 800 ml

Therefore quantity of pure milk vendor sells = 0.8 x 800

                                                                        = 640 ml

Therefore C.P = 640 / 1000 x 10

                     = Rs 6.4

Selling price = 120 % of 10 = Rs 12

Now profit = S.P – C.P

                 = 12 – 6.4

                 = Rs 5.6

Also profit percent = 5.6 / 6.4 x 100

                             = 87.5%
