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
