Answers:

1.B

2.D

3.C

The number of candidates appeared in 1998 be x.

Then, 80% of x = 21200      x =	21200 x 100	= 26500 (required number)

4. D

5. C

The number of candidates qualified in 1999 = (80% of 26500) = 21200.

 Number of candidates qualified in 2000 = (33500 - 21200) = 12300.

Let the number of candidates appeared in 2000 be x.

Then, 60% of x = 12300      x =		12300 x 100		= 20500.
