Question 1195452
.
.
in a market, the price of grades A eggs B eggs and C eggs are in the ratio 7:5:4 respectively.
Nicole was given some money to buy 2 each of grades A & B eggs. 
If she spends just 75% of the money, she will be able to buy an equal number of grades B & C eggs. 
What ratio to the total amount of money will she spend if she chooses to buy only grade C eggs.

            It is just a bad tradition at this forum to post crippled/damaged formulations.


            This time, the formulation is damaged, because the question does not tell, 

            HOW MANY grad C eggs does Nicole really buy.


            I will assume that the question states that she buys 4 grade C eggs 
                    (to support total number of eggs unchangeable: 2 + 2 = 4 eggs).



<pre>
The prices of eggs are 7x (grade A), 5x (grade B), and 4x (grade C).


So, if Nicole buys 2 each of grades A and B, then the total money she spends is  2*(7x+5x) = 2*12x = 24x.


If Nicole buys 4 eggs of grade C, then she spends 4*(4x) = 16x money.


The problem asks about the ratio  16x to 24x.  It is easy to calculate  {{{(16x)/(24x)}}} = {{{16/24}}} = {{{2/3}}}.


<U>ANSWER</U>.  With the given corrections and interpretation, the sough ratio is  {{{2/3}}}.

Solved.
