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.

Q101. If V gets launched before Z does, then which one of the following COULD be true?

• A. R is the second product to be launched.
• B. T is the fourth product to be launched.
• C. Q is the fourth product to be launched.
• D. Z is the sixth product to be launched.

Hint:

Adding V before Z stretches the chain to R, T, V, Z, Q in strict order; work out the earliest and latest position each can sit in.

Answer 1

The Correct Option is D

Adding "V before Z" to the original rules turns R before T before V before Q, Y, S into a longer chain that also threads Z in after V. Build one valid full order first, then check it against every option, adjusting where needed.

1. R is the second product: With Z now stuck after V (and V after T after R), Z can no longer be the one product allowed ahead of R. Nothing at all is left that could launch before R, so R must be first, never second. Rule this out.
2. T is the fourth product: Between R and T, only W is free to slot in (every other product depends on V, which depends on T). That gives room for at most R, W, T across positions 1, 2 and 3, so T tops out at third place. Fourth is out of reach.
3. Q is the fourth product: Five products, R, T, V, Z and Q, are now locked into a strict five-step chain, needing five separate increasing positions. The earliest Q can land is the fifth position. Fourth is too early.
4. V is the fifth product: If V sat fifth, everything that must follow V, namely Z, Q, Y and S, four products in total, would need to squeeze into just three remaining slots (6, 7, 8). That is one product too many for the space available.
5. Z is the sixth product: Build the order R, T, V, W, Y, Z, S, Q. R is first, T second, V third (chain holds). W is fourth (R before W holds, 1 before 4). Y is fifth (V before Y holds, 3 before 5). Z is sixth (V before Z holds, the new rule, 3 before 6). S is seventh (V before S holds, 3 before 7). Q is eighth (Z before Q holds, 6 before 8). Every single rule checks out, and Z does sit in the sixth slot.

Only the fifth option produces a genuine, rule-following order.

Let's summarize:

• V before Z turns the launch order into one long five-step chain, R, T, V, Z, Q, which fixes R first and pushes Q no earlier than fifth.
• Placing V any later than third position leaves too little room for everything that must follow it.

So the option that could be true is "Z is the sixth product to be launched."
