ANSWERS WITH EXPLANATION:

1.       (4)
Required ratio = 50% of 2 : 60% of 3 = 5 : 9.

2.        (2)
Required number = 5800/0.8 = 7250

3.        (5)
Since we don’t know the number of candidates appeared in 2005 and 2006 individually, 
we cannot find the number of qualified candidates.

4.        (3)
Let the number of candidates appeared in 2009 was x. Then
80% of 5100 + 60% of x = 6600
x = 4200

5.        (4)
Total number of men and children staying in locality D together = 2720 + 425 = 3145

6.        (2)

7.        (2)
Total number of children staying in localities C and D together = 648 +425 = 1073

8.        (3)
Required ratio = 1269: 1584 = 141: 176

9.        (3)
Required percentage = (4400*100)/2820 = 156 (approx)
