The proportion of Dye and sugar will remain constant.

Dye/Sugar = (4/9)/(5/9) = x/7.5
=> 4/5 = x/7.5 => x = 4*7.5/5 = 6.

I use a very simple way with fractions to find the calue of x:

$$\frac{4}{9}/\frac{x}{100} = \frac{5}{9}/\frac{7,5}{100}$$

When you solve it you will find that x=6

Can some one explain when to use traditional mixture solutions using grid and when to use simple proportionality equations?

Here you are adding the whole mixture to water, also the ratio water to sugar remains unchanged.

Also you only have to make simple comptutation: 7,5/5*4=6

(A) 6
(B) 6.5
(C) 7.5
(D) 8
(E) 24

Here, let's say that the gallon is 100 litres.
Then sugar in the gallon will be 7.5 litres
Now 5/9x=7.5
'x' is the amoung of the mix poured into gallon
x = (9)(1.5)

Now dye will be 9(1.5)*(4/9)=1.5*4=6

Hence A

Even if you don't find the way to solve it you can straight eliminate answers C,D,E cause the amount of dye is always going to be less given the
4:5 ratio

Hope it helps
Cheers!

In the drink mix, if $$\frac{4}{9} =$$ dye, then

sugar $$= 1 - \frac{4}{9} = \frac{5}{9}$$

If sugar constitutes $$\frac{7.5}{100}$$, then dye percentage $$= \frac{7.5}{100} * \frac{4}{9} * \frac{9}{5} = \frac{6}{100} = 6%$$
