In An Examination, Every Candidate Took Physics Or Mathematics Or Bot

1.	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?
Answer» Let x% candidates TAKE both the subjects. Therefore, Percentage of candidates who opted physics = 65.8% And percentage of candidates who opted mathematics = 59.2% Therefore, x =(65.8 + 59.2 - 100)% = (125 -100)% = 25% ALSO total NUMBER of candidates = 2000 Therefore, Number of candidates who opted both the subjects = 25/100 x 2000 =500. Let x% candidates take both the subjects. Therefore, Percentage of candidates who opted physics = 65.8% And percentage of candidates who opted mathematics = 59.2% Therefore, x =(65.8 + 59.2 - 100)% = (125 -100)% = 25% Also total number of candidates = 2000 Therefore, Number of candidates who opted both the subjects = 25/100 x 2000 =500.

Answer»

Let x% candidates TAKE both the subjects.

Therefore, Percentage of candidates who opted physics = 65.8%

And percentage of candidates who opted mathematics = 59.2%

Therefore, x =(65.8 + 59.2 - 100)%

= (125 -100)% = 25%

ALSO total NUMBER of candidates = 2000

Therefore, Number of candidates who opted both the subjects = 25/100 x 2000 =500.

Let x% candidates take both the subjects.

Therefore, Percentage of candidates who opted physics = 65.8%

And percentage of candidates who opted mathematics = 59.2%

Therefore, x =(65.8 + 59.2 - 100)%

= (125 -100)% = 25%

Also total number of candidates = 2000

Therefore, Number of candidates who opted both the subjects = 25/100 x 2000 =500.
