Lets start with A
Veg- 2:3 ( s:ns)
Non Veg- 4:3 ( s:ns)
If this is actual condition that we have 3 nv ns who can eat hamburgers out of total 12(2+3+4+3). Now we have 15 hamburger so lets multiply this by 5
So total guest=12*5=60- suff
B- 30% veg non students that means 20 % veg students because half of the guests were veg.
15 hamburgers -15 non veg non student- no info about non veg student- insuff
Ans: A

Let assume that ratio given is the actual number so in that case ppl who would be able to eat hamburger would be
nsnv out of (nsnv+snv+snv+sv)
so 3 of 12..now this will account for 3 hamburger we need 15 so multiply by 5 to keep the same ratio
3*5 of 12*5
nsnv out of (nsnv+snv+snv+sv)
