Passage
The following table shows the number of employees of five companies A to E who prefer their own vehicle to reach office, and the percentage of employees who prefer Metro and Bus to reach office. There are only three modes of transport. Company with number preferring own vehicle, percent preferring Metro and percent preferring Bus: A has 184, 68% and 24%; B has 78, 60% and 35%; C has 384, 55% and 30%; D has 182, 70% and 16%; E has 220, 72.5% and 15%. Based on the data in the table, answer the questions that follow.
What is the ratio of the number of employees who prefer travelling by Bus from company C to that of company D?
A48 : 19
B48 : 23
C48 : 13 ✓ Correct
D48 : 11
Correct answer: (C) 48 : 13 — The ratio is 48 to 13, so the answer is 48 : 13.
Explanation
★The ratio is 48 to 13, so the answer is 48 : 13.
★Since the three modes total 100%, the own-vehicle share is 100 minus the Metro and Bus percentages.
★For company C the own-vehicle share is 15%, so 384 is 15% of the total, giving 2560 employees.
★For company D the own-vehicle share is 14%, so 182 is 14% of the total, giving 1300 employees.
★Bus users in C are 30% of 2560, which is 768, and in D are 16% of 1300, which is 208.
★The ratio 768 to 208 reduces to 48 to 13.
★The total for each company is recovered by dividing the own-vehicle count by its own-vehicle percentage.
