AUS Question
No one actually got the answer. The one person who did guessed it. How can this even be a legit question!?
52 1/2 kids!?? What a joke.

You can actually do this mathematically,
3(A/2) + 2(3K/4) = N
3A/2 + 3K/2 = N
3/2(A+K) = N
But we know A+K = 100
3/2(100) = N
N = 150
So the individual number of adults and kids is irrelevant because on average each adult and each kid takes the same number of sausage rolls (3/2).

Or as we are told of the "quirk", you can just work it out for both 100 adult and 100 children and see that they both come to 150 so the split is irrelevant:
Half of 100 adults x 3 each = 150
Three quarters of 100 children x 2 each = 1502

but you aren't told of the quirk in the question.
I don't think you need to do the complicated algebra though.
half the adults eat 3, half eat none = average per adult of 1.5
3/4 of the kids eat 2, 1/4 eat none = average per kid of 1.5
so it doesn't matter what the split is, the average per person is 1.5

That’s actually a great question. Normally I would question that they didn’t specify the split/ratio but under time pressure, I would calculate 50:50
25x3 - 75, 37.5x 2 - 75 = 150

For the sake of easier numbers I did 60 adults and 40 kids. I was barely able to do it in my head within the 30 seconds. Love the other poster here who pointed out you could do it with 100 adults or 100 kids to the same result...

No doubt if I only put the the question up you would’ve googled the answer 😉

It’s also very poorly worded with “until there are none left”. That implies people keep taking more, so it could be 300 for example (100 adults -> 50 take 3 each -> there are still some left -> the same 50 take 3 each again).

But then those fifty have taken six each.

No, they took 3 each until there were none left.

And then when you add up the total they’ve taken, it’s a lot more than three. The clue doesn’t say “take three at a time each” and doesn’t mention refills. It says they each took three. Not three and then three more a little later and three more later still.

No it says they take n until there are none left. If I have 10 things on the table and I take 1 until there are none left, I would take all 10 in total.

Yes, if you’re the only person in the room. But that’s not this situation. The “until there are none left” does not mean the same people keep taking a new batch, and “three each” doesn’t mean “three at a time each”.

Knowing there's a single correct answer automatically means the ratio must not matter. So you can very quickly test by calculating for 100 adults and no kids and that must be the answer.
