The total number of candidates qualified in 2009 and 2010 together was 33500 and the number of candidates appeared in 2009 and 26500. What was the number of candidates appeared in 2010?

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

Answer and Explanation

Answer:20500

Explanation:
Number of candidates appeared in 2009 = 26500
=>Therefore, number of candidates qualified in 2009
=> 80% of 26500 = 21200
=> Number of candidates qualified in 2010
=> 33500 – 21200 = 12300
=> Now, let the number of candidates appeared in 2010 be x.
=> Then, 60% of x = 12300
x = 12300 / 60 x 100 = 20500
