Solving the Egg Puzzle: How Many Eggs Are Left?
Mathematics often comes with a twist in the form of word problems that challenge our ability to reason through logical and numerical steps. One such puzzle involves a tray with 30 eggs and various stages of usage and placement. In this article, we will break down the problem and find the correct number of eggs that remain in the tray.
A Logical Breakdown of the Egg Puzzle
The problem states that a tray contains 30 eggs. The first step is to determine how many of these eggs were used in a cake and how many were cooked. Here’s how we can solve it:
The First Step: Using Eggs for a Cake
Step 1: Half of the 30 eggs are used to bake a cake.
Mathematically, this is calculated as:
Half of 30 1/2 × 30 15
So, 15 eggs were used for the cake.
The Second Step: Cooking the Cake
Step 2: One-fifth of the 30 eggs were cooked as part of the cake-making process.
Mathematically, this is calculated as:
One-fifth of 30 1/5 × 30 6
Hence, 6 eggs were cooked.
The Third Step: Remaining Eggs After Cooking
Step 3: Now, we need to calculate the remaining eggs after accounting for those used in the cake and cooked. This is done by subtracting the used and cooked eggs from the total. After the cake and cooking stages:
Total eggs - Eggs used in cake - Eggs cooked Remaining eggs
30 - 15 - 6 9
Thus, 9 eggs are left in the tray after the cake and cooking stages.
The Final Step: Placing Remaining Eggs in the Refrigerator
Step 4: One-third of the remaining 9 eggs are placed in the refrigerator for storage.
Mathematically, this is calculated as:
One-third of 9 1/3 × 9 3
Hence, 3 eggs are kept in the refrigerator.
Step 5: Subtract the eggs placed in the refrigerator from the remaining 9 eggs.
9 - 3 6
Therefore, the number of eggs left in the tray is 6.
Conclusion
The final answer to the egg puzzle is 6 eggs. This solution demonstrates the importance of breaking down a problem into smaller, manageable steps and performing precise calculations. The key takeaway is that the logic behind the puzzle requires careful attention to each step of the process.
