Problem Analysis

In this problem, we are given that there are plums in a vase. Kostya ate one-fourth of all the plums, and Masha ate one-third of all the plums. We need to determine the initial number of plums in the vase if Kostya ate 3 plums. We also need to identify if there is any unnecessary information in the problem and create a new problem that requires using all the given data.

Problem Solution

Let's solve the problem step by step:

1. Let's assume the initial number of plums in the vase is x. 2. Kostya ate one-fourth of all the plums, which is (1/4)x plums. 3. Masha ate one-third of all the plums, which is (1/3)x plums. 4. Kostya ate 3 plums, so we can set up the equation: (1/4)x = 3. 5. Solving the equation, we find that x = 12. 6. Therefore, the initial number of plums in the vase was 12.

Unnecessary Information

In this problem, there is no unnecessary information. All the given data is required to solve the problem.

Creating a New Problem

Let's create a new problem that requires using all the given data:

Problem: In a basket, there are apples and oranges. Alex ate one-fifth of all the fruits, and Bella ate one-sixth of all the fruits. If Alex ate 4 fruits, how many fruits were there initially in the basket?

In this new problem, we are given that Alex ate 4 fruits and we need to determine the initial number of fruits in the basket. This problem requires using all the given data to find the solution.
