    Two positive numbers are in the ratio 3:4. The sum of thrice the first number and twice the second is 68. Find the smaller number.

    Let me see.

    3(3x) + 2(4x) = 68

    9x + 8x = 68

    17x = 68

    x = 68/17

    x = 4

    3x = 3(4) = 12

    4x = 4(4) = 16

    The smaller number is 12.
