Let's understand this possibility with the help of an equation
Considering two items: fruit pulp and milk
Cost of fruit pulp = $ 5 per liter
Cost of milk = $ 4 per liter
if the cost of the mixture is 4.5 liter, just assume, we can find out their ratio.
assume ratio is a:b
So, forming the equation we get-
5a + 4b = 4.5 (a+b)
therefore, a:b = 1:1
Considering three items: fruit pulp, milk and ice
Here, cost of ice = $ 2 per liter
Cost of fruit shake = $ 3 per liter
If the ratio of fruit pulp, milk and ice is a:b:c
we form the equation as follows-
5a + 4b + 2c = 3 (a+b+c)
In this equation there are three variables. So, in no way we can find ratio of a,b,c
To find values of n variables we need n equations
to find ratio of n variables we need (n-1) equations
My mantra for cracking GMAT:
Everyone has inborn talent, however those who complement it with hard work we call them 'talented'.
