If a and b are positive integers such that a/b = 2.86, which of the following must be a divisor of a?
Choose the correct option.
A) 10	B) 13	C) 18	D) 26	E) 50
a/b = 2.86   a/b = 286/100   a/b = 143/50   a = 143/50*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 143 evenly   (Ignore b as its value unknown; Ignore 50 as in denominator)   Only option B = 13 best fits in   10nswer = 13   10NSWER:10
