Answer: Option C

Explanation:

Total no. of student=150
English=55 Telugu=85
None / neither English nor Telugu=30
No. of Students who speak only one or both=(150-30)=120
=> 120 students can speak english or telugu or both.
So,
No. of Students speak only English= [120-85(telugu)]=35
No. of students speak only Telugu= (120-55) = 65
Remaining 120-(65+35)=20 students can speak both.
