       n = p + 4c

where p is the product of the digits of n, while c is the result when the unitís digit is divided by the tens digit.

(B) For what positive integer bases N< 10 do valid solutions to the above equation exist?

Solution re: Solution - Part (A) + Part(B) | Comment 6 of 7 |
(In reply to Solution - Part (A) by hoodat)

you can use the same equation for part B of the question, W instead of 10

define t=m/n and find all possible values of W<11 by solving

for t=1,2,3...9
