Out of the number of qualified candidates from State X in 2010, the ratio of male to female candidates is 5 : 7. If the number of female qualified candidates from State X in 2010 is 168, what is the number of appeared candidates (both male and female) from State X in 2010?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 480.
Qualified candidates from State X = The number of candidates who appeared in State X in 2010 × 60%
Now,
The ratio of male to female candidates is 5 : 7
If the number of female-qualified candidates from State X in 2010 was 168
so,
⇒ 7x = 168
⇒ x = 24
Number of male = 5x = 120
Total qualified candidates from State X in 2010 = 120 + 168 = 288
Percentage of qualified candidates in state X in 2010 = 60%
We know that 60% of the candidates who appeared qualified.
So,
⇒ 60% = 288
⇒ 1% = 480
Thus,
The number of candidates (both male and female) from State X in 2010 was 480
