The average temperature of Monday, Tuesday and Wednesday was 33°C. While the average temperature of Tuesday, Wednesday and Thursday was 36°C. If temperature of Monday and Thursday was in the ratio 3 : 4, then find the temperature of Monday.
Answer & explanation
Correct answer: option 2
Average of (M + T + W ) = 33
Total temperature of (M + T + W ) = 33 × 3 = 99 ...........(i)
Average of (T + W + Th ) = 36
Total temperature of (T + W + Th ) = 36 × 3 = 108 ...........(ii)
(i) - (ii)
Th - Mon = 9°
Ratio of temperature of, Monday : Thursday = 3 : 4 (given)
∴ 4x - 3x = 9°
x = 9°
Temperature of Monday = 3x = 3 × 9° = 27°
