Question

The drawing club is looking for more members. There are already 5 members, each member has to find 2 more members, and every incoming member must find 2 new members as well, and do this as a layer of recruitment. If at least 80 members are required, members must reach the same level. How long will you get the members you want and the specified conditions?

A. 5th floor

B. 8th floor

C. 7th floor

D. 6th floor

Answer 1

I think the answer should be floor 4 but since floor 5 is the closest I would go for that.

Explanation:

there are 5 members initially in the group if every member has to bring 2 members and those 2 members have to also bring in 2 other members that mean 4 people that are brought in by one person and if there are 5 people in a group that means 20 people are brought in one floor if 20 * 4 is 80 plus the initial 5 members so they only need 4 floors to have at least 80 members.
