Question

• A. $6$
• B. $5$
• C. $4$
• D. $3$

Answer 1

Answer: (C)

$4$

Given : Total no. of passengers $=9$

Number of passengers speaks Kannada $=5$ and $2$ can speak both Kannada and English.

So, there are $3$ passengers who can speak only Kannada.

Suppose, the number of passengers who can speak only English is $x$

$\therefore$ $x=$ Total number of passengers$-$(number of passengers who speak only Kannada $+$ number of passengers who speaks both English and kannada).

$\therefore$ $x=9-(3+2)=4$

Hence, there are $4$ passengers who can speak only English.
