Question : 28 of 40

Marks: +1, -0

Solution:

Average temperature of the whole week = 19.5°

The sum of minimum temperature of 7 days = 20° + 18.6° + 17° + 21.4° + 19° + 19.8° = 115.8°

Minimum temperature on Sunday = x

Total temperature on the whole week = 19.5 × 7 = 136.5°

Temperature on Sunday = Total temperature - Temperature of 7 days

x = 136^{\circ} - 115.8^{\circ} = 20.7^{\circ}
