Finding Grapes Cost Per Kilogram
First, determine the cost of 1 kg of grapes by dividing the total cost by the total weight.
- Cost of 13.5 kg grapes = ₹681.75
- Cost of 1 kg grapes = Total Cost / Total Weight
- Cost of 1 kg grapes = $\frac{₹681.75}{13.5 \text{ kg}}$
Performing the division:
Cost of 1 kg grapes = $₹50.50$
Calculating Cost for 12 kg Grapes
Next, calculate the cost for 12 kg of grapes by multiplying the cost per kilogram by 12.
- Cost of 12 kg grapes = Cost per kg $\times$ 12 kg
- Cost of 12 kg grapes = $₹50.50 \times 12$
Performing the multiplication:
Cost of 12 kg grapes = $₹606.00$
Therefore, the cost of 12 kg of grapes is ₹606.00.
