For one digit to be twice the other, only a given set of numbers satisfy this condition. They are ( 1, 2 ), ( 2, 4 ), ( 3, 6 ) and ( 4, 8 ).
From the above set of numbers, only eight numbers can be formed which are given below.
12, 21, 24, 42, 36, 63, 48 and 84
Thus the answer to the question is 8.
