Seven friends P, Q, R, S, T, U and V, each has a different height. P is taller than only U and R. R is taller than U. Q is taller than S but shorter than T. T is not the tallest among all. The height of how many people is between the heights of Q and R?
Answer & explanation
Correct answer: option 3
1) P is taller than only U and R
⇒ P > U and R
2) R is taller than U
⇒ P > R > U
3) Q is taller than S but shorter than T
⇒ T > Q > S
4) T is not the tallest among all
So, the correct order will be ⇒ V > T > Q > S > P > R > U
So, there are two persons between Q and R.
