Solve the following word problems. 1. Hall A has a chairs. The number of chairs in Hall B is 4 times as many as Hall
A. Hall C has 15 chairs more than Hall A, while Hall D has la + 8) chairs more
than Hall B.
la) Find the total number of chairs in the halls. Give your answer in terms of q.
(b) What is the average number of chairs in each hall?
Give your answer in terms of q.

Step-by-step explanation:

Let a , b , c & d be the no. of chairs in hall A , B , C & D respectively.

Given,

b = 4a

c = a + 15

d = a + 8 + 4a = 5a + 8

Now,

Total no. of chairs (T) = a + b + c + d

                                   = a + 4a + a + 15 + 5a + 8

                                   = 11a + 23

Now,

Average chairs in each hall (Avg) = T/4

                                                       = (11a + 23)/4
