Ok, an easy one to try in your head …
What number is this ? If you add 4 to it you get the same answer as when you multiply it by 4.
(This one wasn’t in the Sunday Times and it didn’t take me a week to figure it out !!)

1 1/3.
Glad it didn’t take a week !
Nicely done.
All of them, to check if any disapprove the statement.
A and 2
What if there is an odd number on the back of B?
You are only have to prove with a vowel on one side have an odd number on the other. What none vowel cards have on the other side doesn’t matter. You also need to turn over 2 to check there is not a vowel on the back of it .
A and 1 then?
Turn over A to check if there is an odd number on the back, don’t turn over B because that is not a vowel, don’t need to turn over 1 because if that is a vowel it proves the statement and if a non vowel it doesn’t concern the statement and turn over 2 to check it isn’t a vowel on the back.
a+4=4a
a= 4/3
Phil
4/3
Exactly what I thought
Yes, as GrahamS says, You need to turn over A and 2. You don’t need to turn over B or 1.
Took a bit of discussion, (which is nice) but everyone got there in the end (I hope).
Well done.
And of course the other answer was 4/3 (or 1&1/3) as several members noted.
Anybody going to state the smallest number of children in the family ?
I’m going to say 4, but my record with these logic things isn’t flash.
Your record is improving
Well done!
We could spice things a little bit
In a particular family, each boy has the same number of sisters and brothers. Each girl has twice as many brothers as sisters.
How many children are they? How many boys? How many girls?
7, 3 girls, 4 boys.
Well done
Nice one Thomas !
