A Leg to Stand On

Stage: 3 Short Challenge Level: Challenge Level:1
206 - the 6 legs of the staff = 200. On average, at each table, there are three table legs, 16 chair legs and 6 customer legs which gives a total of 25 legs per table. 200/25 = 8, hence there are 8 tables and therefore 32 chairs.

This problem is taken from the UKMT Mathematical Challenges.
