    8 and 18

    Explanation:

    This is more math relevant question. lemme try to solve it.

    given coefficients: 2 and 5

    the relation between 2 and 5 = x and y

    x = x; y = 2x + (x/2)

    to see possible numerical combination, we apply one by one all possible combinations in this equation.

    1) 4 and 10

    x = 4

    y = 2x + (x/2)

    = 2 x (4) + (4/2)

    = 8 + 2

    y = 10

    this numerical combination is possible.

    2) 100 and 250

    x = 100

    y = (2 x 100) + (100/2)

    = 200 + 50

    y = 250

    This numerical combination is also possible.

    4) 40 and 100

    x = 40

    y = (2 x 40) + (40/2)

    = 80 + 20

    y = 100

    Given possible combination 40 and 100 is right.

    3) 8 and 18

    x = 8

    y = (2 x 8) + (8/2)

    = 16 + 4

    y = 20

    so, here given possible combination, 8 and 18 is not right. The right combination will form 8 and 20.
