Question
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 = ____________?
Answer: Option D
3 1/X * Y 2/5 = 13¾
=> (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
