Answer is : 39
The average temperature of Monday, Tuesday and Wednesday = \(40 ^ 0 c\)
The sum of their days = 3 x 40 = \(120^0 C\)

The average temperature of Tuesday, Wednesday and Thursday = \(41^0 C\)
the sum of their days = 41 x 3 = \(123 ^0C\)

The temperature of Thursday = \(42^0C\)
Therefore, the temperature Tuesday and Wednesday = 123 – 42 = 81

the temperature of Monday = 120 – 81 = \(39^oC\)
