Hint
Figure out how many chair and table legs are at each table, and then work backwards or guess and check.Answer
42 people are expected to come to the big party.Each table has 6 chairs, so there are a total of 7*4=28 legs at each table.
So, 196/28=7 tables.
Therefore, 7*6=42 guests who are expected to come to the party.

That was quite easy. It was fun though..Thanks.
Easy mental calculation.
can be computed using ratio and proportion.
196 legs means 196/4 = 49.
Therefore there are 49 tables and chairs.
One table sits 6, so 1:6.
if x is number of tables, then x49-x)
or,
1 : 6
x : (49-x)
Cross multiply, you'll get x = 7.
