Answer 1

Answer:

Rs.18

Step-by-step explanation:

Eight kilograms of rice costing Rs. 16 per kg

Cost of 8 kg rice= $16 \times 8 =128$

Four kilograms of rice costing 22 per kg.

Cost of 22 kg rice = $22 \times 4 = 88$

Average of mixture = $\frac{\text{Total cost}}{\text{total weight}}$

Average of mixture = $\frac{128+22}{8+4}$

Average of mixture = 18

Hence  the average price of the mixture is Rs.18

So, Option 1 is true.
