?
In an examination, 35% of the candidates failed in Mathematics and 25% in English. If 10% failed in both Mathematics and English, then how much percent of candidates passed in both the subjects ?
Answer & Solution
Correct Answer:
Option
A
Failed students in Mathematics = 35%
Failed students in English = 25%
Student failed in both subject Mathematics and english = 10%
Student only fail in Mathematics = 35 - 10 = 25%
Student only fail in English = 25 - 10 = 15%
Percentage of passed students in both subjects :
= 100 - [ student fail in Mathematics + student fail in english + student fail in both subject]
= [100 - (25 + 15 + 10)]
= 50%
Failed students in English = 25%
Student failed in both subject Mathematics and english = 10%
Student only fail in Mathematics = 35 - 10 = 25%
Student only fail in English = 25 - 10 = 15%
Percentage of passed students in both subjects :
= 100 - [ student fail in Mathematics + student fail in english + student fail in both subject]
= [100 - (25 + 15 + 10)]
= 50%
