Question

In a group of $115$ people, each has at least one among passport and voter ID. If $65$ had passport and $30$ had both, how many had only voter ID but not passport?

• A. $30$
• B. $50$
• C. $80$
• D. $55$

Answer 1

The correct option is B $50$

Clearly $U=115$
$\Rightarrow$ only $V=115-65=50$
