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

Step 1: See what R at position two forces.
We are told R is the second product launched. Every one of T, V, S, W and Y is tied to R through the rules, T after R, V after T, S after V, W after R, and Y after V, so all five of them have to sit somewhere after position two. That leaves only position one open for a product with no rule pulling it after R.

Step 2: Work out who takes position one.
Q cannot take position one, since Q always has to come after Z. Z itself carries no rule tying it to R, so Z is the one free product that can open the sequence. Z takes position one, with R following right after at position two.

Step 3: Rule out "S gets launched some time before T."
The rules say T comes before V, and V comes before S, so S always lands after T in every valid schedule. S can never come before T, so this statement is always false.

Step 4: Rule out "Y gets launched some time before Q."
Both Y and Q only have to come after V; nothing in the rules fixes their order against each other. Since their relative order stays open, this statement is not something the rules force to hold every time.

Step 5: Confirm W comes before V.
With Z first and R second, positions three through eight have to seat T, V, S, W, Y and Q while keeping T before V before S, and V before both Y and Q. Since W only needs to come after R, and the T-V-S chain together with Y and Q already fills most of that block tightly, the only way to seat every product without breaking a rule is to bring W in early, ahead of V. So W gets launched before V in every valid arrangement once R sits second.

Final Answer:
W gets launched some time before V.
