    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.
