1.  In a class, 20% of the members own only two cars each, 40% of the remaining own three cars each and the remaining members own only one car each. Which of the following statements is definitely true from the given statements ?
A. Only 20% of the total members own three cars each.
B. 48% of the total members own only one car each.
C. 60% of the total members own at least two cars each.
D. 80% of the total members own at least one car.
E. None of these

Answer: Option B

Explanation:

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.
