I would say D, since A and B would be highly irrelevant. C sounds like a possible answer, but could still be viewed as irrelevant since it doesn't actually contain info about MP3 players.
Employee A in 4 years logged travel hours of = 120
Percentage more of travel hours logged by Employee B in 4 years = 20%
Then
Amount of travel hours logged by employee b in 4 years = (120/100) * 120
= 12 * 12
= 144 hours
Then amount of travel hours logged by Employee B after 1.5 years = (144/4) * 1.5
= 216/4
= 54 hours
Amount of travel hours logged by Employee A after 1.5 years = (120/4) * 1.5
= 180/4
= 45 hours.
Number of hours that Employee B had
than Employee A after 1.5 years = (54 - 45) hours
= 9 hours
So emplyee B had logged 9 hours more than Employee A after 1.5 years.
