The code number is 8639

Step-by-step explanation:

Let the number be ABCD

Since code number is between 8500 and 8800,the number in thousand place A = 8.

The digit in hundreds place B is [tex]\frac{3}{4}[/tex] × A = 6

Digit in hundreds place B is 200% of C ,so B= 2×C

So C = 6÷2 = 3

Sum of digits is 26

A+B+C+D = 26

8+6+3+D = 26

D = 26 -17

D = 9

Hence,  the code number is 8639
