Hi!
This is a question from Bond How to Do 11+ Maths book p.49. It is probably older edition.

Some Top Trump cards are won by Arif and Ethan in the ratio 5:4. If Ted has won 20, Ethan will get ____

Am I missing something? Where did Ted come from? It is copied word for word. Please, tell me if you think there is a mistake. If not then how to do it? I have the answer.

I suspect the question has been rewritten to reflect changes in first names and Arif is Ted in disguise ...

Well, If Arif is Ted as suggested above then Ethan will get 16 cards, wouldn't he? But the answer is 25.

The question is wrong then as the ratio would need to be round the other way.

If it was 4:5 then 25 would be the answer for Ethan if Ted = Araf.

Lol! As well as changing Arif's name to Ted you need to either turn the names or the ratio round! I think there are a lot of errors in that question ...............
