Let the total number of people are 'x'

So

According To Given Condition....

$= > \frac{1}{3} x + \frac{5}{12} x + 69 = x \\ = > \frac{4x + 5x}{12} = x - 69 \\ = > 9x = 12x - 828 \\ = > 828 = 12x - 9x \\ = > 828 = 3x \\ = > x = \frac{\cancel{828}}{\cancel{3}} \\ = > x = 276$

So Total Guests Are 276..
