My earlier explanation is some mistake.
The Eight digit no is 52341524.
52341524/4=13085381.
so the Eight digit no and answer is: 52341524.
if any 8 digit no to take then last two digit no is divided by 4. That possibilities are 12,24,32,44,52. so the ans is 5 possibilities. To take this combination of 8 digit no is divided by 4.
