A7. The odometer of a car indicates that the car has traveled $2010 \mathrm{~km}$. It is an odometer with six wheels and no digit after the decimal point, so the reading of the meter is 002010. However, this odometer skips the digit 4 and jumps directly from 3 to 5, for each of the wheels.

How many kilometers has the car actually traveled?
A) 1409
B) 1467
C) 1647
D) 1787
E) 1809
A7. B) 1467 At 9 kilometers, the second wheel from the right jumps. After it has jumped nine times, that is, after 9.9 kilometers, the third wheel from the right jumps. After $9 \cdot 9 \cdot 9=729$ kilometers, the fourth wheel from the right jumps. So in the position 002010, the number of kilometers traveled is equal to $2 \cdot 729+1 \cdot 9=1467$.
