    Clues:

    Glucose is a monosaccharide.
    Maltose is a disaccharide.
    Disaccharides can break down in a hydrolysis reaction to form monosaccharides (Heat does this).
    Benedict's reagent tests for monosaccharides.

    Heat equal volumes of both substances with an excess of Benedict's solution. The one that turns from blue to brick red tests positive for a reducing sugar. Glucose is a reducing sugar, therefore the red colour contains glucose and the blue one contains maltose.
