1) 11 people are behind Jane.
We know 5 more people are ahead then behind. so total is 17. 1 is true. so answer can be A or D.
2) total number are 3 times people behind her.
let people behind her be x. Total people are 3x. We know that people ahead are 5 more than behind. so people ahead are 5+x.
So this will be 3x=x+(x+5)+1. one variable and solvable so 2 is also true.
Answer is D
