Question

in an examination 49% candidates failed in english and 36% failed in hindi and 15% failed in both the subjects. if the total number of candidates who passed in english alone is 630. what is the total number of candidates appeared in examination?

Answer 1

Answer:

Total number of students = 3000

Step-by-step explanation:

Total percentage of students failing in English = 49%

Total Percentage failed in Hindi = 36%

Percentage failed in both = 15%

Percentage passed only in English = Percentage failed only in Hindi

= Percentage failed in Hindi - Percentage failed in both

= 36% - 15%

= 21%

So, according to given condition : 21% of total students = 630

$\text{Total no. of students = }630\times \frac{100}{21}\\\\=3000\thinspace students$
