If a and b are positive integers such that a/b = 1.69, which of the following must be a divisor of a  Choose the correct answer
A) 10  B) 12  C) 11  D) 13  E) 14
a/b = 1.69   a/b = 169/100   a = 169/100*b   We require to find from the available 5 options that must be a divisor of a"   This also means which of the following 5 options can divide 169 evenly   (Ignore b as its value unknown; Ignore 100 as in denominator)   Only option 13 = 13 best fits in   Answer = 13   ANSWER:13
