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 ?
-
- 50%
- 55%
- 57%
- 60%
Correct Option: A
Percentage of students who failed in Maths or English or both
= (25 + 35 – 10)% = 50%
∴ Required percentage
= (100 – 50)% = 50%
Aliter : Using Rule 23,
a = 35%, b = 25% and c = 10%
∴ Passed candidates in both the subjects.
= 100 – (a + b – c)%
= 100 – (35 + 25 – 10)%
= 100 – 50 = 50%
