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 :
[tex] = \frac{12}{100} \: of \: 3500[/tex]
[tex] = \frac{12}{100} \times 3500[/tex]
[tex] =\frac{(12 \times 3500)}{100} [/tex]
[tex] =\frac{42000}{100} \: g[/tex]
[tex] = 420 \: g[/tex]
Final mass = Initial mass - mass that got lost
[tex] = 3500 - 420 \: g[/tex]
[tex] = 3080 \: g[/tex]
∴ The final mass of the cake is 3080 g .
