The following line graph
gives the percentage of the number of candidates who qualified an examination
out of the total number of candidates who appeared for the examination over a
period of seven years from 1994 to 2000.
1.

The
difference between the percentage of candidates qualified to appeared was
maximum in which of the following pairs of years?



2.

In
which pair of years was the number of candidates qualified, the same?



3.

If
the number of candidates qualified in 1998 was 21200, what was the number of
candidates appeared in 1998?



4.

If
the total number of candidates appeared in 1996 and 1997 together was 47400,
then the total number of candidates qualified in these two years together
was?



5.

The
total number of candidates qualified in 1999 and 2000 together was 33500 and
the number of candidates appeared in 1999 was 26500. What was the number of
candidates in 2000?



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.
