  D.  60%

Step-by-step explanation:

You can work multiple choice questions a number of ways. One of the most effective is to eliminate unreasonable choices.

Only two percentages are listed among the answer choices: 60% and 25%. You know that more than half of the lights were green, so the only reasonable choice is 60%.

If we assume lights are either red or green, then 4 of 10 red lights means 6 of the 10 lights were green. As a percentage, that fraction is ...

  6/10 × 100% = 60%
