Answer 1

vom nota fructele cu literele initiale   adica  m; c; p
m+c+p=808
m+c=522
m+p=560
p=808-522
p=286 l
c=808-560
c=248 l
m=560-286
m=274 l

Answer 2

Salut,


m + c + p = 808 l de suc

m + c = 522 l de suc

m + p = 560 l de suc

.............................................


p = 808 – 522 <=> p = 286 l de suc

c = 808 – 560 <=> c = 248 l de suc

m = 808 – (286 + 248) <=> m = 808 – 534 = 274 l de suc

m + c = 522 <=> m + 248 = 522 <=> m = 522 – 248 <=> m = 274 l de suc

m + p = 560 <=> m + 286 = 560 <=> m = 560 – 286 <=> m = 274 l de suc
