On a day in Srinagar, the temperature was `3^(@)C`. At night it dropped to `-3^(@)C`. By how many degrees Celsius did the temperature fall ?

Options

A. `6^(@)C`
B. `3^(@)C`
C. `0^(@)C`
D. `12^(@)C`

Answer

To find out by how many degrees Celsius the temperature fell from day to night in Srinagar, we can follow these steps:

### Step 1: Identify the temperatures
- The temperature during the day is \(3^\circ C\).
- The temperature at night is \(-3^\circ C\).

### Step 2: Set up the equation for temperature change
To find the change in temperature, we need to calculate the difference between the day temperature and the night temperature. This can be expressed as:
\[ \text{Change in temperature} = \text{Day temperature} - \text{Night temperature} \]

### Step 3: Substitute the values
Substituting the known values into the equation:
\[ \text{Change in temperature} = 3 - (-3) \]

### Step 4: Simplify the expression
When subtracting a negative number, it is equivalent to adding the positive:
\[ 3 - (-3) = 3 + 3 = 6 \]

### Step 5: Conclusion
The temperature fell by \(6^\circ C\) from day to night.
