Hi

there are 2*2*2 possible cases. as each a,b and c can carry w(wheat) or r(rice).
we have to find all the plausible cases and from them determine which truck was carrying the same thing.
NOTE:"if a carried wheat then b carries rice" implies that c can carry wheat or rice.
let xxx be what a,b and c are carrying espectively
1.www cant be as when a is w, b is carrying r
2.rrr not poss since wen a is r then c is w
3. wwr not poss since wen a is w, b is r
4.rwr   POSSIBLE
5.rww  not poss since wen b is w then c is r
6.wrw POSSIBLE
7.wrr POSSIBLE
8.rrw POSSIBLE

so truck b is always carrying rice.
