Bala decided to donate `10%` of his salary to PM Care Fund. On the day of donation, he changed his mind and donated `Rs 1800` which was `60%` of what he had decided earlier. How much is his salary ?

Options

A. A)`Rs 36000`
B. B)`Rs 32000`
C. C)`Rs 30000`
D. D)`Rs 40000`

Answer

To find Bala's salary based on the information given, we can follow these steps:

1. **Understand the Donation Amount**: Bala initially planned to donate 10% of his salary. However, he ended up donating Rs 1800, which is stated to be 60% of what he had originally planned to donate.

2. **Calculate the Original Donation Amount**:
- Let the original donation amount (10% of his salary) be represented as \( D \).
- According to the problem, Rs 1800 is 60% of \( D \).
- We can express this relationship mathematically:
\[ 0.6D = 1800 \]

3. **Solve for \( D \)**:
- To find \( D \), we can rearrange the equation:
\[ D = \frac{1800}{0.6} \]
- Calculating this gives:
\[ D = 3000 \]
- Thus, the original donation amount (10% of his salary) is Rs 3000.

4. **Calculate the Salary**:
- Since \( D \) is 10% of his salary, we can express his salary \( S \) as:
\[ 0.1S = 3000 \]
- Rearranging this gives:
\[ S = \frac{3000}{0.1} \]
- Calculating this results in:
\[ S = 30000 \]

5. **Conclusion**: Bala's salary is Rs 30000.

### Summary of Steps:
- Step 1: Understand the relationship between the donation amount and salary.
- Step 2: Set up the equation based on the percentage of the donation.
