The average temperature of Delhi for four days in a particular month is `48^(@)` .If the average temperature of second and third day is `34^(@)` C and the ratio of the temperatures of the first and fourth days is 9:11 , then find out the temperatures of first and fourth days.

Options

A. `45.5^(@)C, 49.9^(@)C`
B. `32.4^(@)C, 39.8^(@)C`
C. `43.4^(@)C, 68.2^(@)C`
D. None of these

Explanation

To solve the problem step by step, we will follow the information given in the question and derive the temperatures for the first and fourth days.

### Step 1: Calculate the total temperature for four days
The average temperature for four days is given as \(48^\circ C\).

The formula for average is:
\[
\text{Average} = \frac{\text{Sum of all observations}}{\text{Number of observations}}
