If there are 4 new houses for every 7 old houses, then the ratio of new houses to old houses is 4/7.
If there are 36 new houses, then the number of old houses is (7/4) * 36 = 63.
Therefore, the answer is C. 63.

If Ryan can install 100 square feet of flooring in 4 hours, then his installation rate is 100/4 = 25 square feet per hour.
In 24 hours, Ryan can therefore install 25 * 24 = <<25*24=600>>600 square feet of new flooring.
Therefore, Ryan can install 600 square feet of new flooring in 24 hours.

If Ross drives 396 miles in 6 hours, then his driving rate is 396/6 = 66 miles per hour.
If we continue to assume that Ross drives at the same rate, then in 12 hours he will drive 66 * 12 = 792 miles.
Therefore, Ross can drive 792 miles in 12 hours.
