Question

There are chairs in the room. If 2 guests share a chair, one chair remains vacant and if each guest sits on a chair 1 guest remains standing. What is the number of guests?​

Answer 1

Step-by-step explanation:

Since it is given that if each guest sits on a chair, one guest remains standing, we can say that there is one less chair. It is also given that when 2 guests share a chair, 1 chair is vacant. Therefore x = 2*2 =4 is the number of guestswith x-1 = 4-1 = 3 as the number of chairs.
