Question

la o fabrica de paine se coc in trei zile 956 paini .In primele 2 zile s-au copt 565 de paini,iar in doua si a treia zi 495 de paini.Cate paini s au copt in fiecare dintre cele trei zilepain

Answer 1

a= prima zi

b= a.doua zi

c = a treia zi

a+b+c=956

a+b=565

b+c=495

565+c=956 /-

c=391 ( a 3 a zi )

b+391=495 /-

b= 104 ( a 2 a zi )

a+104=565 /-

a=461 ( prima zi )

sau :

956-565=391 paini ( a 3 a zi )

495-391=104 paini ( a 2 a zi )

565-104=461 paini ( prima zi )
