Question

la o ferma sunt iepuri albi si cenusiii250 iepuri cenusii si cafenii 201 iar iepuri albi si cafenii 259.citi iepuri sunt la ferma?

Answer 1

a + c = 250
c + caf = 201
a + caf = 259
2 a + 2c + 2 caf = 710
2 ( a + c + caf ) = 710
a + c + caf = 710 : 2
a + c + caf = 355
a + c = 250
250 + caf = 355
caf = 355 - 250
caf = 105
c + caf = 201
c = 201 - 105
c = 96
a + caf = 259
a + 105 = 259
a = 259 - 105
a = 154
deci sunt:
albi = 154 , cafenii = 105 si cenusii = 96
