Solution

The correct option is B 80
Given,
Number of peoples attending a conference = 786
Number of peoples can be seated at each table = 11

Number of tables needed = $\frac{786}{11}$
786 can be rounded to 800.
11 can be rounded to 10.
$∴$ 786 $\div$ 11 = 800 $\div$ 10Therefore, the conference need about 80 tables.
