In case R is the only individual serving on Committee B, which among the following should serve on Committee A?
Explanation
Correct Option - 4
1. Nine individuals Z, Y, X, W, V, U, T, S and R are the only candidates who can serve on three Committees A, B and C and each candidate should serve on exactly one of the Committees.
2. Committee A should consist of exactly one member more than Committee B.
3. It is possible that there are no members of Committee C.
4. Among Z, Y and X none can serve on Committee A.
5. Among W, V and U none can serve on Committee B.
6. Among T, S and R none can serve on Committee C.

In case R is the only individual serving on Committee B.
So, only 2 individuals can serve on Committee A. (From point 2)


Then T and S should serve on Committee A as it is the only position left for T and S.
Hence, ‘T and S’ is the correct answer.
