Logical Interview Question

[europetractor]

Cut or mark each rope into four equal lengths. Remove the last quarter of each piece or set.

Ignite each set. The period of time between the piece that remains lit and the other extinguished equals 45 minutes.

I'd argue this answer is more accurate than that given since you're only igniting the rope once.

Invalid because the rope burns at a different rate throughout its length.

Answer it and ask them to solve something else. When they protest tell them stupid irrelevant interview questions can be asked by both parties.

Invalid because the rope burns at a different rate throughout its length.

If that were true the answer proposed is also wrong.

In either case they did not say the rope burns at a different rate, they said inconsistently.

My answer is actually better now that I think about it. You've two measuring sticks rather than one.

Ignite one end of one rope and multiply the time it takes for it to burn by three quarters.

Yes inconsistently has to mean it can burn 80 percent of its length in 30 seconds and then burn the other part for 59 minutes and 30 seconds. Anyway I don't care about this question.
