Question

In 3 livezi bunicul are 890 de pomi .In prima livada are cat o treime din a doua, iar in a doua livada cat o doime din a treia livada. Cati pomi are

Answer 1

a+b+c=890

a=1/3*b

b=1/2*c

1/3*b+1/2*c+c=890

1/3*1/2*c+1/2*c+c=890

c+3c+6c=890*6 (am adus la acelasi numitor)

10c= 5340

c=534 (a treia livada)

b=1/2*c=1/2*534=267 (a 2 livada)

a=1/3*267=89 (prima livada)
