Initial Share per family = x/6

New Share per family = x/4

Increase share per family = x/4 - x/6 = x/12. Answer C.

Hi All,

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.

GMAT assassins aren't born, they're made,
Rich
