Largest four digit number with repetition = 9999 = x (let)
Smallest Three digit number with repetition = 111 = y (let)
Answer = x-y
= 9999-111
= 9888 -----------------(Ans.)

The largest 4 digit number with repetition is 9999. The smallest 3 digit number without repetition is 102 9999 - 102 = 9897
9876-102=9774The largest 4 digit number, without repetition, is 9876.The smallest 3 digit number is 102.Their difference is 9774.
9876-102 9704

The largest 4 digit number with repetition is 9999. The smallest 3 digit number without repetition is 102 9999 - 102 = 9897
9876-102=9774The largest 4 digit number, without repetition, is 9876.The smallest 3 digit number is 102.Their difference is 9774.
9999-1023 = 8976
9999 - 102 = 9897
If leading zeros are not allowed to make the numbers, then largest = 9876, and smallest = 1023. To get the difference, just subtract: 9876 - 1023 = 8853
9876-102 9704
9888
