Let the total number of people who attended the wedding be x. Obviously they have eaten the food there, As we all do the same :)

Now, According to question:

1/3 of the guests chose beef

5/12 of the guests chose chicken

69 people chose vegetarian

The above data can be expressed as:

Guests who chose beef + Guests who chose chicken + Guests who were vegetarian = Total number of guests..

Plugging the values according to data,

➙ x/3 + 5x/12 + 69 = x

➙ 9x/12 + 69 = x

➙ 12x/12 - 9x/12 = 69

➙ 3x/12 = 69

➙ x/4 = 69

➙ x = 276.

Hence:-

The total number of guests who attended the wedding party were:

$\huge \mathfrak \red{276}$
