Answer & Explanation

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

2. (5)

Since the number of candidates appeared for the exam is not given, we cannot find the number of candidates who cleared the exam.

3. (2)

Required number = 5800/0.8 = 7250

4. (5)

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

5. (3)

Let the number of candidates appeared in 2009 was x. Then

80% of 5100 + 60% of x = 6600

x = 4200
