A function , defined for positive integers , always has integer values. The function has the property that = , where is one of the integers 0, 1, 2, 3.... ( -1). If (119)= 626, then (17) =

a) 10 b) 11 c) 12 d) 13 e)14

Actually I figured it out
It's 12 .
I worked backwords..

(119)= 626

119 = 7 x 17

( 7 17 ) =

(17) + r

with remainder of 38

thus

Spoiler:

(17) = c
