Question

Study the information carefully.
Among M,N,O,P and Q is taller than P.
O is the $2^{nd}$ tallest person.
O is taller than both M and N.
Which of the following is the tallest?

• A. P
• B. Q
• C. M
• D. O

Answer 1

The correct option is B Q

in first line says among $M,N,O,P$and $Q$ all taller than $P$

hence $P<M,N,O,Q$ -(1)

in third line says $O$ is taller than both $M$ and $N$

hence $O>M,N$ -(2)

from above equation (1) and (2) we found that $O>M,N,P$

in second last line says $O$ is 2nd tallest person

hence$Q>O$

hence $Q$ is the tallest person.
