There were 3 glasses containing the same volume of liquid. Mr Lee poured 210 ml of the liquid from Glass A into Glass C, and 150 ml of the liquid from Glass B into Glass C. In the end, the ratio of the volume of liquid in Glass A to the volume of liquid in Glass B was 3:8.
A.) What was the final volume of liquid in Glass A?
B.) What was the volume of liquid in each glass at first?

  • Maths -

    (x-210)/(x-150) = 3/8
    8x-1680 = 3x - 450
    5x = 1230
    x = 246

    all glasses had 246 ml at first

    246-210 = 36 ml left in A
    246-150 = 96 ml left in B

    36/96 = 3:8
