Puzzle: What Number Comes Next 0101=2 0350=2

I saw a puzzle recently stating that 95.1% of Australians can’t get it right, and wondered how they determine the right answer….

This was it:

0101 = 2
0350 = 2
1111 = 0
4508 = ?

So what is the RIGHT answer…

My answer:

0101 has 2 zeros in it = 2
0350 has 2 zeros in it = 2
1111 has no zeros in it = 0
4508 has only 1 zero in it = 1

But if we look at each column of numbers as Col A, Col B, Col C and Col D we could get a different answer, by this method:

(Column B + Column D) minus (Column A + Column C)
0101 (1+1)-(0+0) = 2
0350 (3+0)-(0+5) = -2
1111 (1+1)-(1+1) = 0
4508 (5+8)-(4+0) = 9

However, another answer gives 4508 as equal to 3

I can see how that answer works, can you ?

Each persons mind works differently, so there may be many answers, and not as many wrong ones as is stated, at 95.1% 😉
