- i think ans is 16
bcoz b=gand g-8=2b so now,g=2b+8 by solving two questions we get g=8 and they are asking no of students we get g=b=8 total g+b=8+8=16 - 8 years agoHelpfull: Yes(4) No(2)
- just directly check from the given options
like (1) 32 then 32=(32-8)
32=26
and 26*2=52
option (2) 16=(16-8)
16=8
8*2=16..
Ans = 16..
