If s and t are positive integers such that s/t = 43.18, which of the following could be the remainder when s is divided by t ? Pick one
A) 44
B) 17
C) 54
D) 20
E) 47
s/t= 43.18   s = 43.18t   s = (43 + 0.18)t   s = 43t + (18/100)t   s = 43t + (9/50)t   So remainder will be multiple of 9. The only multiple of 9 is 54.   Ans. 54
