Everyone in the family earns money each month. If the total income of a family per month is $9000 and the median income is $3000, how many members are there in the family?
Options: A) 2 B) 3 C) 4 D) 5 E) 6
There must be more than two members.   If there are four members, then the middle two average $3000 for a total of $6000, and the highest earner must earn at least $3000 which puts the total at $9000 minimum. The lowest earner pushes the total past $9000 so there can not be four family members.   There must be three family members.   The answer is 3.
