I have one question if someone could help me how to calculate it: If I have some amount of money (Euros). What the amount I have if I need to have the amount once doubled plus a half of the amount plus a quarter of the amount plus 1 to have 100 Euros?

  • Hello and thanks. This is a quiz question and I wonder how to calculate it right. I get the exact result but wonder what would be a more convenient way to get he result. This is how i got it. (36+36+(36/2)+(36/4)+1)=100 So the amount I currently have is 36 but this is just a calculation if you know the amount of Euros in advance, but i wonder how to calculate it with a guess that we don't know it?

    So to make it more clear once more: I have some amount of Euros. What's the amount if have have to add the same amount once more + a half of the amount + a quarter of it + 1?

Suppose we have some amount of money, we call this $x$. Then, based on you question, we want $$x+x+\frac{x}2+\frac{x}{4}+1=100.$$ Simplifying yields $$\frac{11x}{4}=99.$$ Then $$x=\frac{99\cdot 4}{11}=36.$$
