What is the number of Model-Q cars sold in all cities together?
A31255
B31355
C31455
D31555 ✓ Correct
Correct answer: (D) 31555
Explanation
The number of Model-Q cars is 31555, so the answer is 31555.
For each city, take its share of 90000 and then the Q part of its model ratio.
City A gives 90000 times 14.3 percent times 7 of 18, which is 5005.
City B gives 8100, City C gives 4968 and City D gives 5040.
City E gives 4536 and City F gives 3906.
Adding these gives 5005 plus 8100 plus 4968 plus 5040 plus 4536 plus 3906.
That equals 31555.
