    Answer: ( 1 ). – 9 : 1

    Let two numbers be X and Y.

    According to Question,
    X + Y = 20       . . .  . .  . ..(i)
    and X – Y = 25        . . . . .  .  . . . (ii)

    Now, solving equations (i) & (ii), we get
    2X = 45
    X = 22 . 5  ….. . .. … .(iii)
    put the value of X in eqn. (i) , we get Y = – 2 . 5

    The ratios of these two number is X : Y = – 22 . 5 : 2.5 = – 9 : 1
