Answer:

 Divisibility rule of 12 : Number divisible by both 3 and 4.

⇒  Divisibility rule of 3 : A number is divisible by 3 if the sum of the digits is divisible by 3.

⇒  Divisibility rule of 4 : A number is divisible by 4,  if the last two digits are a multiple of 4.

⇒  123452=1+2+3+4+5+2=17

.⇒  78968=7+8+9+6+8=28

⇒  123452 and 78968 are not divisible by 3 so its not divisible by 12

⇒  79998=7+9+9+9+8=42, it is divisible by 3.

⇒  Last two digit 98 is not divisible by 4

∴   79998 is not divisible by 12.

⇒   79968=7+9+9+6+8=39, it is divisible by 3

⇒   Last two digit 68 are divisible by 4.
