A. 45%

B. 35%

C. 20%

D. 40%

Answer: Option D

Solution(By Examveda Team)

Failed students in Hindi = 35%
Failed students in English = 45%
Student failed in both subject hindi and english = 20%
Student only fail in hind = 35 - 20 = 15%
Student only fail in English = 45 - 20 = 25%
Percentage of passed students in both subjects :
= 100 - [ student fail in hindi + student fail in english + student fail in both subject]
= [100 - (15 + 25 + 20)]
= 40%
