The answer is he is a visitor i.e. he is telling the truth
Reason:
If he was a native i.e. a liar then his answer would would have been "she says she is a native" for both cases because
If she was visitor: she would have said she is a visitor and he would have lied that she is a native
If she was native: she would have lied and again say that she is a visitor and he would have lied that she is a native.

The answer may be native, because without asking her the salesman said the answer, he says only in the condition when he is a liar, so liar means native

Its not the n+1th fibonacci no., the ans is nth fibanacci no.
for eg:-
if no of steps is 3 then n=3
if no of steps is 4 then n=5
if no of steps is 5 then n=8

Total dist travelled=(1/6+1/6)=1/3miles
relative speed=(60+60)=120miles per hour
therefore,
time=dist/speed
=(1/3)/120=(1/360)hours=10secs(1hr=3600secs).tmhasan7

1. Its obvious that since the trains travel towards each other the speed is 60+60 miles/hr2. The two trains will take 2/6 miles to cross themselves, since the length of the train is 1/6 miles.3. If it...
