Answer: (3) 42 degree Celsius 

Explanation:-
The average temperature for Monday, Tuesday and Wednesday = 40 degree
Therefore, the sum of temperature of Monday, Tuesday and Wednesday = 3 x 40 
 = 120 degree

The average temperature for Tuesday, Wednesday and Thursday = 41 degree
Therefore, the sum of temperature of Tuesday, Wednesday and Thursday = 3 x 41
 = 123 degree

The temperature of Thursday = 45 degree 
Then, the temperature of Tuesday and Wednesday = 123 – 45
 = 78 degree

So, the temperature on Monday = 120 – 78
 = 42 degree Celsius. 

Hence, the correct answer is option (3) 42 degree Celsius.
