Question

Joy organized a wedding.
Guests had to choose their meal from beef, chicken or vegetarian.
1/3 of the guests chose beef
5/12 of the guests chose chicken
23 of the guests chose vegetarian
How many guests were at the wedding?

Answer 1

the guests that chose the beef and chicken are 1/3+5/12=4/12+5/12=9/12
that leaves 3/12 guests that chose vegetarian food (stupid vegans)
3/12------->23
12/12----->X
X=[(23×1)/(3/12)]
X=92
there was 92 guest in total
