A little cerebral exercise

[griff]

Judging by the original clues I reckon there can only be one possible answer. 1982

I think Tricky is still trying understand where the 8 comes from

If he asks nicely I’ll tell him.

You old lads are to intelligent for me alas.

No, that was an easy one.

I didn't understand it even when I was told the answer

Here goes Chalky................

Frenchy gave 4 clues:

(1). 7 6 1 9 = Two good numbers but not correctly positioned

(2). 4 7 6 3 = No good numbers

(3). 0 4 5 1 = One good number but not correctly positioned

(4). 5 9 4 2 = Two good numbers and correctly positioned

(5). The code is made up of 4 different numbers

Forget the order of the clues, it’s just there to confuse you. Look at (5) first because it says that all the numbers in the code are different. Then look at (2) - none of the numbers are there so the four different numbers must be either 0, 1, 2, 5, 8 or 9. We’ll call this “the list”.

Now look at (1). The only 2 numbers on the list are 1 and 9 so now we have 2 numbers in the code.

Now look at (3). Only one of the numbers is in the code and we already know that it’s 1 as demonstrated in the last paragraph. That also means that 0 and 5 are NOT in the code. The only numbers left in our list are 1,2, 8 and 9.

(4) shows us that the 9 and the 2 are correctly positioned so the code is _9_2. From (1) we can see that the 1 cannot be the third number, so it must come first and the remaining number, 8, will be third.

Hence 1982.

That hasn't helped tbh honest Griff infact it's probably confused me even more
