1. The problem involves understanding the relationship between the total cost and the number of packets of candies. 2. We are given a total cost of Rs. 12 for 8 packets of candies. 3. To find the cost per packet, we use the formula for unit cost: $$\text{Cost per packet} = \frac{\text{Total cost}}{\text{Number of packets}}$$ 4. Substitute the given values: $$\text{Cost per packet} = \frac{12}{8}$$ 5. Simplify the fraction: $$\frac{12}{8} = \frac{3}{2} = 1.5$$ 6. Therefore, the cost per packet of candy is Rs. 1.5. 7. This means each packet costs 1.5 units of currency.
