Options

A. 113
B. 123
C. 96
D. None of these

Answer

To find the average number of notebooks bought by Rahul, Anil, Mohit, and Madhu, we will follow these steps:

### Step 1: Calculate the total number of notebooks bought
First, we need to add the number of notebooks bought by each person:

- Rahul: 86 notebooks
- Anil: 124 notebooks
- Mohit: 132 notebooks
- Madhu: 150 notebooks

Total notebooks = 86 + 124 + 132 + 150

### Step 2: Perform the addition
Now, let's add these numbers step by step:

1. Add Rahul's and Anil's notebooks:
\( 86 + 124 = 210 \)

2. Now, add Mohit's notebooks:
\( 210 + 132 = 342 \)

3. Finally, add Madhu's notebooks:
\( 342 + 150 = 492 \)

So, the total number of notebooks bought is 492.

### Step 3: Count the number of people
Next, we count the number of people who bought notebooks. In this case, there are 4 people (Rahul, Anil, Mohit, Madhu).

### Step 4: Calculate the average
To find the average, we divide the total number of notebooks by the number of people:

Average = Total number of notebooks / Number of people
Average = 492 / 4

### Step 5: Perform the division
Now, we perform the division:

1. Divide 492 by 4:
- 4 goes into 4 once (1), remainder 0.
- Bring down the next digit (9), 4 goes into 9 twice (2), remainder 1.
- Bring down the next digit (2), 4 goes into 12 three times (3), remainder 0.

So, \( 492 ÷ 4 = 123 \).

### Conclusion
The average number of notebooks bought by Rahul, Anil, Mohit, and Madhu is **123**.
