Neerja is going to Chandigarh from Delhi. She has travelled 270 km. This is `90%` of the total distance between Delhi and Chandigarh. What is the distance between the two cities ?

Answer

To find the distance between Delhi and Chandigarh, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**:
Neerja has traveled 270 km, which is stated to be 90% of the total distance between Delhi and Chandigarh. We need to find the total distance.

2. **Set Up the Equation**:
Let the total distance between Delhi and Chandigarh be represented as \( x \) kilometers. According to the problem, 90% of this total distance is equal to 270 km. We can express this mathematically as:
\[ 90\% \text{ of } x = 270 \]

3. **Convert Percentage to Decimal**:
To work with the percentage, we convert 90% to a decimal. This is done by dividing by 100:
\[ \frac{90}{100} \times x = 270 \]
This simplifies to:
\[ 0.9x = 270 \]

4. **Solve for \( x \)**:
To find \( x \), we need to isolate it. We can do this by dividing both sides of the equation by 0.9:
\[ x = \frac{270}{0.9} \]

5. **Calculate the Value**:
Now, we perform the division:
\[ x = 270 \div 0.9 = 300 \]

6. **Conclusion**:
The total distance between Delhi and Chandigarh is \( 300 \) kilometers.

### Final Answer:
The distance between Delhi and Chandigarh is **300 km**.
