Problema Solution
Eggs, flour and sugar are mixed in the ratio 3:5:4 by mass to bake a cake. If the mass of the cake is 720g find the mass of eggs
Answer provided by our tutors
let
e = the mass of the eggs
f = the mass of the flour
s = the mass of the sugar
e : f : s = 3 : 5 : 4
thus we can write
e = 3k
f = 5k
s = 4k
where k is positive integer
the mass of the cake is 720g that is
e + f + s = 720
3k + 5k + 4k = 720
12k = 720
k = 720/12
k = 60
e = 3k = 3*60 = 180g of eggs
the mass of the eggs is 180g.
