Option 1: 280
Option 2: 300
Option 3: 260
Option 4: 240
Correct Answer: 280
Solution :
Average = $\frac{\text{Sum of Observations}}{\text{Number of Observations}}$
Average = $\frac{8 \times {(45+35+36+44+28+22)}}{6}$ = 280
$\therefore$ The average number of tyres per brand is 280.
Hence, the correct answer is 280.
