Jamie is making his annual Christmas cake.
The ratio of flour to sugar to treacle to almonds to butter is 4:3:2:1:1
Jamie uses 150g of treacle in the mix.
The weight of Jamie’s Christmas cake is reduced by 10% after it’s baked.
Find the weight of the cake after it is baked.
Answer:
Weight of ingredients:
Flour – 300g (150 * 2)
Sugar – 225g (150/2 * 3)
Treacle – 150g
Almonds – 75g (150/2)
Butter – 75g (150/2)
Total weight of raw ingredients = 11 * 75g = 825g
Cooked weight = 0.9 x 825 = 742.5g
