以下是易伯华SAT频道为大家整理了SAT数学Problem Solving练习题(29)，供考生们参考，以下是详细内容。
Question 29: Out of all of the houses characterized in the table below, what
is the percentage of new ranches?
HousesOldNewTotal
Ranch23?30
Colonial?40?
Total23??
(a) 10%
(b) 12%
(c) 15%
(d) 25%
(e) 8%
Answer: The number of new ranches will be 30 - 23 = 7. We need to find the
total number of houses.
The number of old colonials will be 23 - 23 = 0, and the total number of
colonials will be 40 + 0 = 40.
The total number of houses will be the total number of ranches + the total
number of colonials, 30 + 50 = 70. We can rewrite the table:
HousesOldNewTotal
Ranch23730
Colonial04040
Total234770
The percentage of new ranches will be (7 / 70)·100 = 10%
