Six students, P, Q, R, S, T and U each are of different heights. P is taller than only two students. T is taller than only one student but shorter than exactly four students. S is taller than only four students but is not the tallest. Q is taller than none of the students. R is not the tallest. Who is the tallest student?

Correct option is B

Given:

Six students P, Q, R, S, T and U.

Solution:

P is taller than only two students.

_> _> _> P > _ > _

T is taller than only one student but shorter than exactly four students.

_ > _ > _ > P > T > _

S is taller than only four students but is not the tallest.

_ > S > _ > P > T > _

Q is not taller than any student.

_ > S > _ > P > T > Q

R is not the tallest.

_ > S > R/Q > P > T > Q/R

And U will place the remaining position,

U > S > R > P > T > Q

Here, U is the tallest.

Thus, correct option is (b)
