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

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

B. 1994 and 1995 Wrong Right

C. 1997 and 1998 Wrong Right

D. 1998 and 1999 Wrong Right

E. 1999 and 2000 Wrong Right

Answer : 1994 and 1995

Explanation : The differences between the percentages of candidates qualified to appeared for the give pairs of years are:
For 1994 and 1995 = 50 - 30 = 20.
For 1998 and 1999 = 80 - 80 = 0.
For 1994 and 1997 = 50 - 30 = 20.
For 1997 and 1998 = 80 - 50 = 30.
For 1999 and 2000 = 80 - 60 = 20.
Thus, the maximum difference is between the years 1997 and 1998.

C. 20500 Wrong Right

D. 19000 Wrong Right

Answer : 20500

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 * 100)/60 = 20500.

What is the ratio of the production to export of wheat in 1999?

A. 64:25 Wrong Right

B. 50:27 Wrong Right

C. 62:27 Wrong Right

D. 54:29 Wrong Right

E. 64:27 Wrong Right

Answer : 64:25

Explanation : Let us assume that the production of wheat in 1998 is 8000 and
Therefore the export of wheat in 1998 is 1500
The total production in the given five years
8000 x 100 / 20 = 40000
Total export in the given five years = 1500 x 100 / 10 = 15000
Production of wheat in 1999 = 9600
Export of wheat in 1999 = 3750
Required ratio = 9600/3750 = 64/25

B. 465 Wrong Right

C. 512 Wrong Right

D. 655 Wrong Right

E. None of these Wrong Right

Answer : 512

Explanation : Given, export of wheat in 1999 = 200 million tones
Total export in five years = 200 x 100 / 25 = 800 million tones
Export in 1998 = 80 million tones
Production of wheat in 1998 = 80 x 16/3
= 426.67
Total production in the five years
426.67 x 100 / 20 = 2133.33
Production of wheat in 1999 = 2133.33 x 24 / 100 = 512
