Answer 1

Answer:

642

Step-by-step explanation:

since there are 10 digits, and the first four are

9, 9, 8, 7 and last four 3, 5, 5.

the order will be 9987- - -355.

the only distinct numbers left are 1, 2, 4, 6.

for the three missing numbers to be distinct and the greatest possible we will pick the greatest numbers, Which is 642.
