Please help with this one...
A school gate needs the correct combinationof four digits in the correct order
When 5648 is tried 2 digits are wrong
When 3628 is tried 2 digits are wrong
When 3147 is tried 2 digits are wrong
When 5629 is tried 2 digits are wrong
When 1258 is tried all the digits are wrong
What is the correct combination of digits?
Thank you
1258 are all wrong so applying this,
*64* so 64 are correct
36** so 36 are correct
3*47 so 347...
*6*9.....69
Collecting in ORDER, 3,6,4, then 7 or 9? As two had to be wrong in 3*47, 7 is wrong leaves, 3649.
