In a group of students, 70% can speak English and 65% can speak Hindi. If 27% of the students can speak none of the two languages, then what percent of the group can speak both the languages?
A)38%
B) 62%
C) 28%
D) 23%
Correct Answer:
B
Solution :
Let total number of students = 100 \[\therefore \]27 students speak none of the two languages. It means only 73 students speak either Hindi or English or both. Let x students speak both languages. \[\therefore \] \[73=70-x+x+65-x\] \[\Rightarrow \] \[x=70+65-73=62\]
