If s and t are positive integers such that s/t = 36.42, which of the following could be the remainder when s is divided by t ? Choose the correct choice from the following choices:
A) 42
B) 43
C) 83
D) 20
E) 45
s/t= 36.42   s = 36.42t   s = (36 + 0.42)t   s = 36t + (42/100)t   s = 36t + (21/50)t   So remainder will be multiple of 21. The only multiple of 21 is 42.   Ans. 42
