Answer 1

Given:

Total members in the club = 100% (Let's assume total members = 100 for easier calculation)

20% of the members own only two cars each.

40% of the remaining members own three cars each.

The rest of the members own only one car each.

Concept Used:

We need to calculate the percentage of members who own only one car.

Calculation:

⇒ Number of members owning two cars = 20% of 100 = 20 members

⇒ Remaining members = 100 - 20 = 80 members

⇒ Members owning three cars = 40% of 80 = 32 members

⇒ Remaining members = 80 - 32 = 48 members

These 48 members own only one car each.

⇒ Percentage of total members owning one car = (48/100) × 100

⇒ Percentage = 48%

∴ The percentage of the total members who own one car each is 48%.
