Six cars, namely P, Q, R, S, T, and U, have different speeds when compared with each other. No two cars have the same speed. Only two cars have more speed than P. U has less speed than P but more than S. So, three cases are possible i.e., Case 1, Case 2 and Case 3.
Case 1:
___ > ___ > P > U > S > ___
Case 2:
___ > ___ > P > U > ___ > S
Case 3:
___ > ___ > P > ___ > U > S
R has more speed than P but less than T. Q has less speed than S. So, Case 2 and Case 3 are invalid.
Case 1:
T > R > P > U > S > Q
Finally, we get,
T > R > P > U > S > Q
Only one car has lower speed than S.
