The average of the temperatures recorded at noontime from Monday to Sunday is 31^\circ\text{C}. If the lowest temperature recorded is 30^\circ\text{C}, then what is the <strong>MAXIMUM</strong> of temperature that is possible to record at noontime on any one of the days?

  1. A. 34^\circ\text{C}
  2. B. 35^\circ\text{C}
  3. C. 36^\circ\text{C}
  4. D. 37^\circ\text{C}

Correct Answer: D. 37^\circ\text{C}

Explanation

Total sum for 7 days = 7 \times 31 = 217^\circ\text{C}. To maximize one day's temperature, the other 6 days must be the lowest possible (30^\circ\text{C}). Maximum temperature = 217 - (6 \times 30) = 217 - 180 = 37^\circ\text{C}.
