Question

A Mobile number consists of ten digits. The first four digits of the numbers are 9,9,8 and 7 . The last three digits are 3,5 and 5. The remaining digits are distinct and make the mobile number, the greatest possible number. What are these digits?

Answer 1

The number is of the form:
9 9 8 7 _ _ _ 3 5 5

We have to fill the _ with distinct numbers

The remaining usable numbers are : 1, 2, 4, 6

We require only 3 larger numbers : 2, 4, 6

The largest number possible using these three numbers is: 6 4 2

So filling the _ with required greatest number is
9 9 8 7 6 4 2 3 5 5

The answer is :
9987642355
