Please refer to the attachment. The answer is B. Can someone please explain how to do this question. I am unsure where to begin. What I've picked up: time difference of 41minutes, all digits should be different for two successive minutes. But what numbers should I start with as this could take ages.

You cpuld write the two clocks as an 8 digit number. Fitst four are 1 clock. Hours in digits 1,2,5,6 Minutes in 3,4,7,8 Hours: 5,6 are the same as 1,2 or +1. What can these values be Minutes are: +41 or -19. A bit of testing should get you there?

What I've understood from this is: clock 1: 12:34 clock 2: 56:78 Is this what you meant?
First of all, how does the person asking the question know their neighbour has a digital clock in her living room? You don’t realise until looking back just how creepy some of those questions were

Maybe, maybe he was snooping around, these questions just need a backstory to them to clear things, also two digital clocks? One faster than the other at completely different times? Sounds like a crazy woman to me
abcdefgh Clock 1: ab:ef Clock 2: cd:gh Then just work out the hours and minutes.
For hours we have 0-24 i.e. 25 different possibilities. How do we narrow this down? I just read up an explanation and they said that the only possible combination for hours is 19 and 20. But, how did they even get to this conclusion?

For a question like this you have to get your hands dirty. Just try some values and work out why thats the only +1 combimation with no repeats. Its similar for the minutes as well.

Not realy. Its problem solving rather than applying a formula so you have to get stuck in. The hours reasoning should be quick and tbh, the minutes is fairly straightforward, the tens must be 3,5 and the digits 6,7,8.
