Question

Directions for Questions 97 to 101: A company launches eight products, Q, R, S, T, V, W, Y and Z, in one of the four metros of India. The products are launched one after another over a period of six months in 2006. The order of launch follows these conditions:

• V is launched before both Y and Q.
• Q gets launched after Z.
• T gets launched before V but after R.
• S gets launched after V.
• R gets launched before W.

Q100. If R is the second product to be launched, which one of the following MUST be true?

• A. S gets launched some time before T.
• B. T gets launched some time before W.
• C. W gets launched some time before V.
• D. Y gets launched some time before Q.

Hint:

Work out which single product is forced into position one once R is fixed at position two, then see how tightly the rest of the chain has to fit around W.

Answer 1

The Correct Option is C

The rules for this launch schedule are: V comes before Y and before Q, Q comes after Z, T comes before V but after R, S comes after V, and R comes before W. We are told R launches second, and need the statement that must always be true.

1. S gets launched some time before T: T always comes before V, and V always comes before S, so S is always after T. This can never be true.
2. T gets launched some time before W: Both T and W only need to come after R; the rules never fix their order against each other, so this does not hold in every arrangement.
3. W gets launched some time before V: With R fixed at position two, every one of T, V, S, W and Y is pushed into positions three onward, and only Z is free to open the sequence at position one, since Q can only follow Z. Working through how tightly T, V, S, Y and Q have to be seated after position two shows W has to be brought in early, ahead of V, to keep the whole schedule consistent. This holds in every valid arrangement.
4. Y gets launched some time before Q: Y and Q both only need to follow V, with no rule ordering them against each other, so this is not forced.

Let's summarize:

• Z is forced into position one and R into position two, since Z is the only product free of any rule tying it after R.
• S before T is impossible outright, and T before W, Y before Q are both left open by the rules.
• W before V is the one relationship the schedule cannot avoid once R is second.

So the statement that must be true is that W gets launched some time before V.
