- 5 leave 3 (5n + 3)
- 6 leave 1 (6n + 1)
Here is a list of multiples of the integer n that satisfy the three conditions.

Answer:
2. 1
Step-by-step explanation:
the point at which the y axis is passed through is (0,1)
1/3+5/12=4/12+5/12=9/12=3/4 of guests choose meat
1-3/4=1/4 of guests are vegetarians
so
23 guests is 1/4 of all guests
23*4=92 all guests
