Answer:
There may be 3 tables or 1 table.
Explanation:
If we factorize 12 into its prime factors then we get 12 = 2 × 2 × 3
If there are an odd number of tables and each table has an equal number of chairs and there are a total of 12 chairs, then the possibilities of the number of tables are 1 and 3.
{Since 1 and 3 both are odd numbers}
Now, for 3 tables there will be 4 chairs each to make the total chairs (3 × 4) = 12 and for 1 table there will be 12 chairs in the table to make the total number of chairs (1 × 12) = 12. (Answer)
