• B. 46 °C
• C. 49 °C
• D. 45 °C

Answer 1

Answer:

C. 49 °C

The average temperature on Sunday, Monday and Tuesday was 45 °C. Then total temperature of Sunday, Monday and Tuesday = 45° × 3 = 135°C total temperature of Monday, Tuesday and Wednesday = 42° × 3 = 126°C As on Wednesday it was exactly 40 °C.Then total temperature of Monday and Tuesday = (126° – 40°)C = 86°C The temperature of Sunday = total temperature of Sunday, Monday and Tuesday - total temperature of Monday and Tuesday = (135° - 86°)C = 49 °C
