Answer for yesterday's Brain Teaser
Which digit must be replaced with ‘X’ in 8X37X4, so as to make it divisible by 24?
If 8X37X4 is to be divisible by 24, then it must also be divisible by 3 and 8.
To be divisible by 8, X must be an even number.
To be divisible by 3; 22 + 2X (= 8 + X + 3 + 7 + X + 4) is a multiple of 3.
Digit 4 is the only such number which satisfies both the conditions.
Hence, the required digit is 4 so that 843744 is divisible by 24.
