    Let the Number be x so,

    4/5*x - 75% *x = 40

    4/5x - 75/100*x = 40

    4/5*x - 3/4*x = 40 x/20 = 40 x = 800

    so the answer is 800

    Let’s say that the unknown number is “x”. 4/5=80% or 0.8x. 75% is 0.75x.

    The question goes thus:

    0.8 x-0.75 x=40 or x(0.8–0.75)=40; x=40/0.05;

    Multiplying numerator and denominator by 100 to get a non decimal denominator, we get x=4000/5 or x=800

    You can also do fractions if you don’t care for decimal points.

    4/5x-3/4x=40 (since 7%% is 3/4)

    x(4/5–3/4)=40; x (1/20)=40; x=40*20=800 Goutam Dutta

    Let the number be X,

    4/5 of X = X . 4/5 x 100 = 80%

    80% - 75% = 5% X . 5 % = 40

    X =( 100 /5) x 40 =800

    The answer is 800. Carl Bryan
