Names & Numbers

Thanks to Mike and Ruth VanderMeer from Canada, we can present you the following names and numbers puzzle:

Four words add up to a fifth word numerically:

...mars
..venus
.uranus
.saturn
-------- +
neptune


Each of the ten letters (m, a, r, s, v, e, n, u, t, and p) represents a unique number in the range 0 .. 9. Furthermore, numbers 1 and 6 are being used most frequently.

The Question: What number does neptune represent?


Answer: The easiest way to solve this problem is by writing a computer program that systematically tries all possible mappings from the numbers onto the letters. This will give you only one solution which meets the condition that the numbers 1 and 6 are most frequently used:

Conclusion: neptune equals 1078610.
