Answers
1. B. 1220
Explanation :
x = Female candidates in 2001
40% of 6400 = 2560
(3/8)x of 2560 = 960
y = Female candidates in 2005
40% of 1040 = 416
y = (5/8)*416 =260
Total = 960 + 260 = 1220

2. B. 61%
Explanation :
x = percent of qualified male candidates
x = (8/13)*100 = 61%

3. C. 180
Explanation :
54% of 750 = 405
x = percent of qualified female candidates
x = (4/9)*405 = 180

4. C. 17:25
Explanation :
28% of 600 = 168
Female Candidates = 168 – 68 = 100
68 : 100 => 17:25

5. C. 528
Explanation :
72% of 600 = 432
60% of 1040 = 624
432 + 624 = 1056 = 1056/2 = 528

6. E. 5:7
Explanation :
28% of 600 = 168
Female candidates = 70
Male candidates = 168 – 70 = 98
=> 70:98
=> 5:7

7. B. 225
Explanation :
20% of 750 = 150
= 750 + 150 = 900
25% of 900 = 225

8. A. 60%
Explanation :
Number of qualified candidates in 2002 and 2005 = 866
2005: 40% of 1040 = 416
866 – 416 = 450
(450/750)*100 = 60%

9. B. 800
Explanation :
x = qualified candidates; y = Appeared Candidates
(3/13)*x = 120
x = 520
65% of y = 520
y = 800

10. A. 15%
