37.

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

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.

 Vki said: (Sep 13, 2020) It is already said that 20 persons own only 2 cars. So, (100-20=80) those are remaining students.
