Can anyone help me with this comparison question. I know the answer is "B) Quantity B is greater" but I am hoping to find the best method for dealing with this kind of question.
Question:
The average (arithmetic mean) of 100 measurements is 23, and the average 50 additional measurements is 27.
Quantity A- The average of the 150 measurements.
Quantity B- 25
Thanks ahead of time
