A cake is made from the ingredients listed below.

Oksana_A [137]

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 :

$= \frac{12}{100} \: of \: 3500$

$= \frac{12}{100} \times 3500$

$=\frac{(12 \times 3500)}{100}$

$=\frac{42000}{100} \: g$

$= 420 \: g$

Final mass = Initial mass - mass that got lost

$= 3500 - 420 \: g$

$= 3080 \: g$

∴ The final mass of the cake is 3080 g .
