Cost of 10 g of Saffron is ₹ 280. If John bought 2 kg of Saffron, then how much money did he spend?

The correct option is D ₹ 56000
Given:
Since, 1 kg = 1000 g, therefore 2 kg = 2000 g
Cost of 10 g Saffron = ₹ 280
Therefore,
Cost of 1 g Saffron = ₹ $\frac{280}{10}=₹28$
Cost of 2000 g Saffron = $₹28\times 2000=₹56000$
