Answer

To solve the problem, we need to determine how many months Mr. Walia will take to save Rs 72,000 if he saves 36% of his monthly salary of Rs 25,000.

### Step-by-Step Solution:

1. **Calculate Mr. Walia's monthly savings:**
- Mr. Walia saves 36% of his monthly salary.
- Monthly salary = Rs 25,000.
- Monthly savings = 36% of 25,000.
- To calculate 36% of 25,000, we convert the percentage to a decimal:
\[ 36\% = \frac{36}{100} = 0.36 \]
- Now, calculate the savings:
\[ \text{Monthly savings} = 0.36 \times 25000 = 9000 \]
- So, Mr. Walia saves Rs 9,000 every month.

2. **Determine how many months it will take to save Rs 72,000:**
- We need to find the number of months (let's call it \( x \)) required to save Rs 72,000.
- We can set up the equation:
\[ 9000 \times x = 72000 \]
- Now, solve for \( x \):
\[ x = \frac{72000}{9000} \]
- Simplifying the right side:
\[ x = 8 \]

3. **Conclusion:**
- Mr. Walia will take **8 months** to save Rs 72,000.
