Problem Analysis

Vasya went to the store to buy 1 kilogram of candy. However, he only brought enough money for exactly 1 kilogram of candy. When he arrived at the store, he found out that the price of candy had increased by 40 rubles. Now, Vasya's money is only enough to buy 840 grams of candy. We need to determine the new price per kilogram of candy after the price increase.

Solution

Let's assume the original price per kilogram of candy was P rubles. After the price increase, the new price per kilogram of candy is P + 40 rubles.

We know that Vasya's money is now enough to buy 840 grams of candy. Since 1 kilogram is equal to 1000 grams, we can set up the following equation:

P * 840 / 1000 = Vasya's money

Simplifying the equation, we have:

P = (Vasya's money * 1000) / 840

Now, we can substitute the given value of Vasya's money (840 grams) into the equation to find the new price per kilogram of candy.

Calculation

Let's calculate the new price per kilogram of candy:

P = (840 * 1000) / 840 = 1000 rubles

Therefore, the new price per kilogram of candy after the price increase is 1000 rubles.

Answer

The new price per kilogram of candy after the price increase is 1000 rubles.
