Percentage of Candidates Qualified to Appeared in an Examination Over the Years

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?

[A]. 24500
[B]. 22000
[C]. 20500
[D]. 19000

Answer: Option C

Explanation:

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 ) = 20500.
60

The number of students that qualified is LESS than the number of students who appeared (that is, those who turned up to take the exam they were eligible for). This makes no sense!?

Please Resolve my Doubts.

x = Digital Sum(12300) X D.Sum(100)/D.Sum(60).

= D.Sum(6X1)/D.Sum(6) = 1.

Eliminate click option D in which case D, sum should be used.

Can you please explain me with detailed how 80% of 26500=21200?

I did not understand this step.

80/100 * 26500 = 21200.

First know the formula,

Percentage = (Qualified /Appeared)x 100.
Given in 1999 candidates appeared was 26500 and from graph percentage in 1999 is 80

Therefore using above formula,
80 = (Q/26500)x 100.
Q in 1999 =21200.

And also given candidate qualified in both years is 33500.

Therefore,
Q(1999)+Q(2000) = 33500.
Q(2000)=33500-21200 = 12300.

They asked to find number of candidates in 2000 means they are asking appeared candidates
Again use above percentage formula,

60 = (12300/A)x100.
A = 20500.
