Problema Solution
in a rectangular auditorium 300 chairs are arranged in rows and columns.no. of chairs in each column is more than 5. find no.of chairs in each row and each column
Answer provided by our tutors
let
x = the number of chairs in each column
y = the number of columns
no. of chairs in each column is more than 5:
x > 5
the total number of chairs is x*y = 300
300 = x*y > 5y
5y < 300
y < 60
of the number of chairs if more than 5 then the number of columns is less than 60.
for example for x = 10 chairs, there are y = 300/10 = 30 columns.
