For every positive integer n, form the number n / s(n), where s(n) is the sum of the digits of n in base 10. What is the minimum value of n/s(n) for 10 <= n <= 99.	Choose one.
A) 1.2
B) 3.45
C) 1.9
D) 2
E) 4
possibility to sum of digits 10   i.e   (1.9),(2,8),(3,7),(4,6),(5,5)   we get s/s()n are 1.9,2.8,3.7,4.6,5.5   so the minimum possibility of s/s(n)=19/10=

<output>19/10 = around 1.9</output>
1.9   ANSWER:1.9
