Question

A cake is made from the ingredients listed below.

500 g flour, 450 g butter, 470 g sugar,
1.8 kg mixed fruit, 4 eggs (70 g each)
The cake loses 12% of its mass during cooking.
What is its final mass?​

Answer 1

To make a cake :-

Quantity of flour needed = 500 g

Quantity of butter needed = 450 g

Quantity of sugar needed = 470 g

Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g

Quantity of eggs needed = 70 × 4 = 280 g

It's weight after adding all the ingredients =

=500 + 450 + 470 + 1000 + 800 + 280

= 3500 g

Mass that got lost while baking the cake :

= 12 % of 3500

`= (12)/(100) \: of \: 3500`

`= (12)/(100) * 3500`

`=((12 * 3500))/(100)`

`=(42000)/(100) \: g`

`= 420 \: g`

Final mass = Initial mass - mass that got lost

`= 3500 - 420 \: g`

`= 3080 \: g`

∴ The final mass of the cake is 3080 g .
