• D. $80$% of the total members own at least one car
• E. None of these

Answer 1

Answer: (B)

$48$% of the total members own only one car each

Let total number of members be $100$.
Then, number of members owning only $2$ cars $=20$.
Number of members owning $3$ cars $=40$% of $80=32$.
Number of members owning only $1$ car $=100-(20+32)=48$.
Thus, $48$% of the total members own one car each.
