Abner challenges Benny to find out his secret number. On being requested by Benny for some clues, Abner says:
- It is a 4-digit number.
- The thousands digit is precisely 5 less than one-sixth of the number formed by the concatenation of its hundreds and tens digit (from left to right).
- The hundreds digit is precisely 1.8 more than 1/40 of the number formed by the concatenation of its tens and units digits (from left to right).
- Its tens digit is precisely 2 less than 5/4 times the units digit.
Determine Abner's secret number from the above-mentioned statements.
Clue 4: Last two digits are either 34 or 88
Clue 3: Hundreds digit is 88/40 + 1.8 = 4, because 34/40 + 1.8 is not integral
Clue 2: Thousands digit 48/6 - 5 = 3
Full number is 3488
Shorter analytical solution
