The line chart given below shows the delay (in minutes) on arrival of a train on 6 consecutive days D1, D2, D3, D4, D5 and D6.
What is the average daily delay (in minutes) on these 6 days?
Show answer & explanation
Correct answer: B
Explanation
Given:
D1 = 44, D2 = 34, D3 = 37, D4 = 5, D5 = 17, D6 = 48
According to the formula:
Average = Sum Total / Count
Sum Total = 44 + 34 + 37 + 5 + 17 + 48 = 185
Average = 185 / 6 = 30.83
