Clubhouse

A clubhouse contained only chairs and tables. Each chair had 4 legs and each table had 3 legs. A group of scouts arrived; each sat on a chair, 2 chairs were left empty, and the total number of legs in the room (people + furniture) was 101. How many chairs were in the clubhouse?

Final Answer:

n =  17

Step-by-step explanation:


101 = 3+2·4 + (4+2)·(n-2)

6n = 102


n = 102/6 = 17

n = 17
