The number of cars passing the road near a colony from 6 am to 12 noon has been shown in the following histogram.
During which hour(s) is the number of cars passed more than the average number of cars passed from 6 am to 11 am?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 7-8 am, 8-9 am, 9-10 am
Average car passing the road = (Total cars passing the road)/5
Total cars passing the road (up to 11 AM) = (70 + 105 + 130 + 115 + 95) = 515
Average car passing the road (up to 11 AM) = 515/5 = 103 cars
Thus, in the time 7 - 8 am, 8 - 9 am, and 9 - 10 am, the number of cars passed more than the average number of cars passed from 6 am to 11 am.
