Answer 1

Mon­day's temperature recorded as 39. Average temperature for monday, tuesday and wednesday is 36.3 degrees.
Sum of temperature for monday, tuesday and wednesday is 36.3 × 3 = 108.9℃
Sum of temperature for tuesday and wednesday is 108.9 - 39 = 69.9℃
The average temperature for tuesday, wednesday and thursday is 36.7 degree.
Sum of temperature for tuesday , wednesday and thursday is 36.7 × 3 = 110.1℃
Temperature on thursday 110.1 - 69.9 = 40.2℃
