Set A: 3, r, 8, 10
Set B: 4, g, 9, 11
The terms of each set above are given in ascending order. If the median of Set A is equal to the median of Set B, what is the value of g – r?	Choose one:
A) - 2  B) - 1  C) 0  D) 1  E) 2

Rationale: so we have even no . of elements in the set so median is the average of middle two numbers ( r + 8 ) / 2 = ( g + 9 ) / 2 g - r = - 1 answer b
Answer: B
