Use the number system with Radix or base 7. i.e System which includes digits 0 1 2 3 4 5 6. SO Option B is correct.

+

....1.....4

-------------

...........8 (by normal addition of unit places we get 8, but in answer its 1, so if we take base 7 then 8%7 = 1)

...........1 (also 1 carry to tens place)

.....4.....1 (the required answer)

so base 7
