Positive integers indicated by x and y satisfy 3 1/x * y 2/5 = 13 3/4, the fractions being in their lowest terms, then x = ? and y = ? Options:
A) x = 4, y = 8  B) x = 4, y = 4  C) x = 2, y = 4  D) x = 8, y = 4  E) None of these
3 1/x * y 2/5 = 13¾   =&gt; (3x + 1) / x + (5y + 1) / 2 += 55 / 4   only choice (4) i.e x = 8 and y = 4 satisfies the given equation.   3 (1/8) * 4 (2/5) = (25 / 8 ) * (22 / 5) = 55/4 = 13¾   ANSWER:x = 8, y = 4
