Answer 1

v/...../
t/...../+240
V/..../+240+500
1160-240-240-500=180
180:3=60
vitelul=60kg
taurasul=60+240=300kg
vaca=300+500=800kg
140+380+640=1160

Answer 2

tauras-a
vitel-b
vaca-c
a=240+b
a=c-500   c=a+500
a+b+c=1160
240+b+b+a+500=1160
2b+240+b+740=1160
3b+980=1160
3b=1160-980
3b=180
b=180:3
b=60
a=240+60=300
c=300+500=800
