Question

If 15 kg of fish cost ₹ 1800, what is the cost per kg?

• A. ₹ 180
• B. ₹ 120
• C. ₹ 140
• D. ₹ 160

Answer 1

The correct option is B ₹ 120

Cost of 15 kg of fish = ₹ 1800

We need to find the cost of 1 kg of fish.

$\text{Unit price}=\frac{\text{Total price}}{\text{Quantity}}=\frac{₹1800}{15}=₹120$

Thus, 1 kg of fish costs ₹ 120.
