The price of sugar fell by 20℅. How much more sugar can you buy now with the same amount of money as before the fall?

To solve this problem, we introduce two conditional variables “X” and “Y”, through which we denote the amount of money and the initial price of sugar, respectively. Then, the new sugar price will be equal to Y – (20% x Y) / 100% = Y – 0.2Y = 0.8Y. Therefore, X / 0.8Y of sugar can be bought for the new price. At the old price it was possible to buy X / Y sugar. Now let’s find out what percentage the new amount of purchased sugar is in relation to the original amount of sugar. As a result, we get (X / 0.8Y / X / Y) x 100% = 125%. Therefore, you can buy 125% sugar – 100% = 25% more.
Answer: 25%.
