The number of passengers who traveled by train A in all three days = (240 +200 +400) = 840
The number of passengers who traveled by train C in all three days = (280 + 160 +360) = 800
Required ratio = 840: 800 = 21: 20

The number of passengers who traveled by train B in day 1 and day 3 together = 300 + 260 = 560
The number of passengers who traveled by train D in day 2 and day 3 together = 280 + 300 = 580
Required difference = 580 - 560 = 20

The number of passengers traveled by train B in day 2 and day 3 = 420 + 260 = 680
The number of passengers traveled by train E in day 2 and day 3 = 400 + 220 = 620
Required average = [680 + 620]/2 = 650

The number of passengers who traveled by train A in Day 1 and 2 together = 240 + 200 = 440
And, number of passengers who traveled by train E in same days = 320 + 400 = 720
So, required % = (720 - 440)/720 × 100 = 38.88%
