Comprehension:
The given line graph shows the percentage of the number of candidates who qualified in an examination out of the total number of candidates who appeared for the examination over a period of seven years from 1994 to 2000. Answer the following two questions based on the graph
If the number of candidates that qualified in 1998 was 21200, what was the number of candidates that appeared in 1998?
Solution
Let x be the number of candidates who appeared for the exam.
From the graph, we can infer that in 1998, 80% of the students passed the exam, which is given to be 21200.
So, $$80\ \%\ of\ x=\ 21200$$
=>$$\ \frac{\ 80}{100}\times\ x=\ 21200$$
=> $$\ \frac{\ 4}{5}\times\ x=\ 21200$$
=>$$\ \ x=\ \ \frac{\ 5}{4}\times\ 21200$$
.'. x=26500, Option C
