Solution

Given : The average temperature on Wednesday, Thursday,and Friday = 38°C
â‡’ Sum of temperatures on Wednesday, Thursday,and Friday = 3 Ã— 38°C = 114°C
also temperature on Friday = 39°C
â‡’ Sum of temperatures on Wednesday and Thursday = Sum of temperatures on Wednesday, Thursday,and Friday - Temperature on Friday = 114°C - 39°C = 75°C
Now, average temp.on Tuesday, Wednesday,and Thursday = 31°C
â‡’ Sum of temperatures on Tuesday, Wednesday,and Thursday = 3 Ã— 31°C = 93°C
â‡’ Temperature on Tuesday = Sum of temperatures on Tuesday, Wednesday,and Thursday - Sum of temperatures on Wednesday and Thursday = 93°C - 75°C = 18°C
