The average of the temperatures recorded at noontime from Monday to Sunday is 31°C. If the lowest temperature recorded is 30°C, then what is the maximum of temperature that is possible to record at noontime on any one of the days
Elementary MathematicsStatistics
- A34°C
- B35°C
- C36°C
- D37°C
Explanation
The week's total is 7 × 31 = 217°C. To make one day's temperature as large as possible, set the other six days to the minimum, 30°C each. Then the remaining day is 217 − 6×30 = 37°C — option D.
