Correct Answer: 6
Solution :
The number of cycles = 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 + 25 = 720.
Total time = 12 hours
The average number of cycles parked
= $\frac{\text {Total number of cycles parked between 9 a.m. and 8 p.m.}}{\text{Total time}}$.
= $\frac{720}{12}$
= 60
The number of cycles parked above average is 95, 75, 85, 65, 75, and 65 i.e. 6 times.
Hence, the correct answer is 6.
