Math Problem Statement
(b) A group of children bought some apples. Each apple is cut into 4 equal pieces and divided by 1 piece, leaving 3 pieces. And when each apple was cut into 3 equal pieces, two pieces were not enough. Find the number of children and the number of apples by writing a pair of simultaneous equations, taking the number of children as x and the number of apples as y.
Solution
To solve the problem, we need to establish two equations based on the information provided.
Let's denote:
- as the number of children.
- as the number of apples.
Step 1: Formulate the first equation
The first scenario states that each apple is cut into 4 equal pieces. Each child receives 1 piece, leaving 3 pieces.
So, the total number of pieces obtained from apples is . If each of the children receives 1 piece, the equation will be:
Step 2: Formulate the second equation
The second scenario states that each apple is cut into 3 equal pieces. Two pieces were not enough for all the children.
So, the total number of pieces obtained from apples is . Since two pieces were not enough, it implies that the total number of children is two less than the total number of pieces:
Step 3: Set up the simultaneous equations
The two equations we derived are:
Step 4: Solve the simultaneous equations
Set the equations equal to each other to eliminate : Subtract from both sides: Add 3 to both sides:
Now that we have , substitute it into one of the original equations to find . Using Equation 2:
Final Answer:
- The number of children () is 17.
- The number of apples () is 5.

Here are 5 related questions that might interest you:
- What happens if each apple is cut into 5 equal pieces?
- How would the equations change if two pieces were left in the first scenario?
- Can you solve a similar problem where each apple is divided into 6 pieces?
- What is the solution if instead of apples, oranges are divided into 4 and 3 pieces?
- How would the solution differ if the number of leftover pieces in the first scenario was 4 instead of 3?
Tip: Always double-check your equations by substituting your final values back into the original conditions to ensure accuracy.
