total amount x
share per family before 2 families left = x/6
share after families left = x/4
share difference = x/4-x/6 = x/12
each family will be paying x/12 extra

Hi alanforde800Maximus,

This question can be solved by TESTing VALUES.

If the total cost of the condo was X dollars, and there are 6 families, we should choose a value of X that is a multiple of 6...

Let's TEST X = 12

Thus, originally each family was supposed to pay $2 for the condo. When two families pull out of the deal, then (2)($2) = $4 has not been paid for. The remaining 4 families have to make up for that shortfall, meaning that each pays an extra $1. There's only one answer that matches.

Final Answer: C
