Passage
The following table shows the percentage distribution of candidates qualifying a Common Entrance Test (CET) in six cities A to F during 2020 and 2021, along with the ratio of males (M) to females (F) among the qualified candidates. The total number of qualified candidates across all six cities was 3800 in 2020 and 4600 in 2021. In 2020 the distribution percentage and M:F ratio were: A 13 percent and 8:5, B 27 percent and 11:8, C 11 percent and 7:4, D 20 percent and 2:3, E 8 percent and 5:3, F 21 percent and 13:8. In 2021 they were: A 24 percent and 5:7, B 15 percent and 12:11, C 23 percent and 15:8, D 17 percent and 8:9, E 8 percent and 1:3, F 13 percent and 5:8. Based on the data, answer the questions that follow.
What is the difference between the number of male candidates qualified from City B in 2020 and City A in 2021?
A134 ✓ Correct
B144
C168
D182
Correct answer: (A) 134 — The difference is 134, so the answer is 134.
Explanation
★The difference is 134, so the answer is 134.
★In 2020 City B has 27 percent of 3800, which is 1026 qualified candidates, in the ratio 11 to 8.
★So the males are 11 of 19 parts of 1026, which is 594.
★In 2021 City A has 24 percent of 4600, which is 1104 qualified candidates, in the ratio 5 to 7.
★So the males are 5 of 12 parts of 1104, which is 460.
★The difference is 594 minus 460.
★That equals 134.
