Some Thoughts re: An analytic start and a calculator finish Comment 3 of 3 |
(In reply to An analytic start and a calculator finish by Charlie)

All  I know without calculator :

1. N is a 3-digit number,  between 300 and 400.

2. The units digit of N  is 7 (7931 being the cycle, 3 is in 19th place)

So the number   is  3?7 -      to find  "?"  - few calculators trials.

... Who called it a p&p problem?
