On a test day, 100 candidates took a psychometric test. The first group of 60 candidates scored on an average (arithmetic mean) 68 points. The second group of 40 candidates scored on an average half of the average score of the first group.
Average of all 100 candidates = Sum of the scores of all 100 candidates / 100 = \(\frac{(60 * 68) + (40*.05*68) }{ 100}\) = 54.08
Since 54.08 < 55, the answer is B.
