Solution

The correct option is C ₹245
Cost of 1 kg of oranges = ₹ 70.
First, we will find the cost of 3 kg and then the cost of half kg separately. We can add them to find out the total cost.
Cost of three kg of oranges = ₹ 70 x 3 = ₹ 210.
Cost of $\frac{1}{2}$ kg of oranges = $₹ 70 \times \frac{1}{2} = 70 \div 2 = ₹ 35$
Total cost of three and half kg of oranges = ₹ 210 + ₹ 35 = ₹ 245.
