The problem could be like this.
While planning for the party, orders for chairs and tables were made such that for every 8 chairs, there were 3 tables. Find the number of chairs that would be ordered for if 15 tables were required.
Let x represent the number of chairs
Let y represent the number of tables
Therefore,]
x:y = 8:3
x/y = 8/3
When y = 15, then
x/15 = 8/3
By cross multiplying, it becomes
3x = 8 * 15 = 120
x = 120/3
x = 40
Therefore, 40 chairs would be ordered for 15 tables
