Who among the following sits with W on Bike C?

Options

A. S
B. P
C. Q
D. T

Answer

D

Explanation

Step 1.
From the information given in the question,
No two persons from Congress and no two persons with Loud speakers occupied seats on the same bike. No two persons carry same thing on the same bike. Q is from BJP. P and S are from the same party. P, V and W are from same party. It means that P, V, W and S are from Congress as there are four persons from each party. Similarly, R, T and U will be from BJP. P and V sit on bike A and bike B respectively. W, who is carrying a Loud speaker is not sitting on bike D.

Step 2.
Proceeding with the remaining information,
Two persons who are from the same party cannot sit on the same bike. That means W is not travelling on bike A or B. So, W will be the one who is travelling on bike C and S will be the one who is travelling on bike D. R sits with S. That means R is also travelling on bike D. Q is not sitting on the same bike with V and with W. That means Q is travelling on bike A. Both U and W are carrying the same things. That means U is carrying a loud speaker and travelling on bike B. Similarly, T will be the one who is travelling on bike C. It is also given that two persons who are sitting on the same bike cannot carry same thing. So V and T carry a flag. P and V are carrying the same thing. As P is carrying a flag, Q will be the one who carries a Loud speaker. Q and S are not carrying the same thing.
So, S is carrying a flag and R is carrying Loud Speaker. If Q carries flag, the other conditions of R and S can’t be possible so Q carries a loud speaker. So, we get our final solution as,
