Answer:
if the odometer does not show not show two digits that is 2 and 4 effectively it uses a system with base 8 the usual base 8 system uses the digits 0 to 7
The mapping of the corresponding digits are as follows:
0 1 3 5 6 7 8 9
0 1 2 3 4 5 6 7
does the odometer reading in the actual base 8 system is 13000 because 5 corresponds to 3
converting 13000 to base 10
1*8^4 + 3*8^3 + 0*8^2 + 0*8^1 + 0*8^0 = 5632 is the answer
hope u like the answer it will help u :)
