In an examination, every candidate took Physics or Mathematics or both. 65.8% took Physics and 59.2 % took Mathematics. The total number of candidates was 2000. How many candidates took both Physics and Mathematics ?
-
- 750
- 500
- 250
- 125
Correct Option: B
Let x% candidates take both the subjects.
Percentage of candidates who opted Physics = 65.8%
and percentage of candidates who opted Mathematics = 59.2%
∴ x = (65.8 + 59.2 - 100)% = (125 - 100)% = 25%
Also, total number of candidates = 2000
∴ Number of candidates who opted both the subjects
= 25 x 2000/100 = 500
