Question

Solve the following word problems.

Answer 1

Answer:

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
