Seven books P, Q, R, S, T, U, V are to be placed on a shelf

• P is placed immediately to the right of Q.
• R is placed immediately to the left of S.
• T is placed to the extreme left.
• V is placed immediately to the right of R.

Which book is placed in the middle?

In this question, R is placed immediately to the left of S and V is placed immediately to the right of R. Each statement means R S and R V respectively. How can both R be immediately to the left of S and V together? Is this an incorrect question? Has anyone raised an objection on this?

If "MOON" is coded as "LNLM" and "SUN" is coded as "RVM" then using the same pattern, "STAR" can be coded as:

A) RSBQ
B) RSUQ
C) RUSB
D) RTAQ
E) RSBP

Can anyone solve this? I narrowed it down to A or B but can't exactly guess which it will be. The correct answer is A.
