Question

this question is really confusing me so help would be really appreciated

Answer 1

Answer:

276.

Step-by-step explanation:

Let the Total guests = x

guests who preferred :

beef : 1/3x

chicken : 5/12x

vegetarian : 69

equation is-

1/3x + 5/12x + 69 = x

or, x - 9/12x = 69

or, 3/12x = 69

or, x = 69/(3/12)

or, x = 276

Therefore total guests were 276.

Hope you'll understand it.
