Average between two sets of numbers is closer to the set withmore numbers?  Choose the correct answer
A) 70	B) 80	C) 90	D) 95	E) 98
If on a test three people answered 90% of the questions correctly and two people answered 80% correctly, then the average for the group is not 85% but rather 3×90+2×805=4305=86.3×90+2×805=4305=86.   Here, 90 has a weight of 3 =&gt; it occurs 3 times.   Whereas 80 has a weight of 2 =&gt; it occurs 2 times.   So the average is closer to 90 than to 80 as we have just calculated.   80
