Question

The temperatures of a city recorded during a week are 42°, 35°, 44°, 33°, 39°, 45° and 42°. The average temperature is 

A) 42° 

B) 35° 

C) 39° 

D) 40°

Answer 1

Correct option is (D) 40°

Average temperature \(=\frac{\text{Sum of temperatures in a week}}7\)

\(=\frac{42^\circ+35^\circ+44^\circ+33^\circ+39^\circ+45^\circ+42^\circ}7\)

\(=\frac{280^\circ}7=40^\circ\)

Answer 2

Correct option is  D) 40°
