If a dozen buns cost Rs 36.60. What is the cost of one bun?

Options

A. Rs 1
B. Rs 3.05
C. Rs 2.25
D. Rs 4

Answer

To find the cost of one bun when a dozen buns cost Rs 36.60, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the problem**: We know that a dozen buns (which is 12 buns) costs Rs 36.60. We need to find the cost of one bun.

2. **Set up the equation**: The cost of one bun can be found by dividing the total cost of the dozen buns by the number of buns in a dozen.
\[ \text{Cost of one bun} = \frac{\text{Total cost of a dozen buns}}{\text{Number of buns in a dozen}} \]

3. **Substitute the values**:
\[ \text{Cost of one bun} = \frac{36.60}{12} \]

4. **Perform the division**:
- First, we can simplify the division.
- 12 goes into 36 three times (since \(12 \times 3 = 36\)).
- Now, we have 0.60 left to divide by 12.
- To make it easier, we can consider 60 instead of 0.60.
- 12 goes into 60 five times (since \(12 \times 5 = 60\)).
- So, we have:
\[ \frac{36.60}{12} = 3.05 \]

5. **Conclusion**: The cost of one bun is Rs 3.05.

### Final Answer:
The cost of one bun is Rs 3.05.
