Question:
If 9 kg of sugar costs ₹ 238.50, how much sugar can be bought for ₹ 371?
Solution:
Let the quantity of sugar bought for ₹371 be x kg.
| Quantity(in kg) | 9 | x |
| Price(in ₹) | 238.50 | 371 |
The price increases as the quantity increases. Thus, this is a case of direct proportion.
$\therefore \frac{9}{238.50}=\frac{x}{371}$
$\Rightarrow x=\frac{9 \times 371}{238.50}=14$
Thus, the quantity of sugar bought for ₹371 is 14 kg.
