    D) 80% of the total members own at least one car.

    Correct Answer: B

    Solution :

    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 \[=100-\left( 20+32 \right)=48\] Thus, 48% of the total members own car each.
