What is the ratio of the number of cars sold in City C to the number of Model-Q cars sold in City D?
A19:5
B27:8
C23:7 ✓ Correct
D33:10
Correct answer: (C) 23:7
Explanation
The ratio is 23 to 7, so the answer is 23 to 7.
Cars sold in City C are 90000 times 18.4 percent, which is 16560.
In City D the Q part of the ratio 4:3:2 is 3 of 9.
So Model-Q cars in City D are 90000 times 16.8 percent times 3 of 9, which is 5040.
The ratio is 16560 to 5040.
Dividing both by 720 gives 23 to 7.
So the ratio is 23 to 7.
