Answer 2

Average price of the mixture is 20.59 Rs. per liter.

Step-by-step explanation:

Price of one liter milk = ₹ 25

Price of 12 liters of milk = 25 × 12

                                       = ₹ 300

Price of one liter of mineral water = ₹ 10

Price of 5 liter of mineral water = 5 × 10

                                                    = ₹ 50

5 liters of mineral water is mixed with 12 liters of milk.

The amount of mixture = 12 + 5

                                      = 17 liters

Cost of the mixture = 300 + 50

                                = ₹ 350

Average price of per liter mixture = $\frac{\text{cost of mixture}}{\text{quantity of mixture}}$

                                                       = $\frac{350}{17}$

                                                       = 20.588

                                                       ≈ ₹ 20.59

Average price of the mixture is 20.59 Rs. per liter.
