Three boys earned a total of Rs 235.50. What was the average amount earned per boy?

Answer

To find the average amount earned per boy, we can follow these steps:

### Step 1: Understand the formula for average
The average amount earned per boy can be calculated using the formula:
\[ \text{Average} = \frac{\text{Total Amount Earned}}{\text{Number of Boys}} \]

### Step 2: Identify the total amount earned and the number of boys
From the question, the total amount earned by the three boys is Rs 235.50, and the number of boys is 3.

### Step 3: Substitute the values into the formula
Now, we substitute the values into the formula:
\[ \text{Average} = \frac{235.50}{3} \]

### Step 4: Perform the division
To divide 235.50 by 3, we can do the following:

1. Convert 235.50 into a fraction for easier calculation. This can be expressed as:
\[ 235.50 = \frac{23550}{100} \]

2. Now, divide 23550 by 3:
- 3 goes into 23 (7 times) = 21 (remainder 2)
- Bring down the next digit (5), making it 25. 3 goes into 25 (8 times) = 24 (remainder 1)
- Bring down the next digit (0), making it 10. 3 goes into 10 (3 times) = 9 (remainder 1)
- Bring down the next digit (0), making it 10 again. 3 goes into 10 (3 times) = 9 (remainder 1)
- Since we have no more digits to bring down, we can stop here.

Thus, we find that:
\[ 235.50 \div 3 = 78.50 \]

### Step 5: Write the final answer
Therefore, the average amount earned per boy is:
\[ \text{Average} = 78.50 \text{ Rs} \]
