If 9 kg of sugar costs Rs. 238.50, how much sugar can be bought for Rs.371?

Answer»

More the amount of sugar, more will be the cost. So it is a direct proportion.

Let the amount of sugar be x kg, \(\frac{9}{238.50}=\frac{\text{x}}{371}\)

⇒ 238.50 × x = 9 × 371

⇒ x = \(\frac{9\,\times\,371}{238.50}\) = 14kg
