The following line graph gives the percentage of the number of candidates who qualified for an examination out of the total number of candidates who appeared for the examination over a period of seven years from 1994 to 2000.
Percentage of Candidates who Qualified to Appeared in an Examination Over the Years
The total number of candidates who qualified in 1999 and 2000 together was 33500 and the number of candidates who appeared in 1999 was 26500. What was the number of candidates in 2000?
24500
22000
20500
19000
Correct answer is C
The number of candidates qualified in 1999 = (80% of 26500) = 21200.
Therefore 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)/60 ) = 20500
