If A=2/3(B=C) and c=1/2(A+B) and A+B+C=3000, then find C.

• A+B+C=3000
  C=3000-(A+B) [ C=1/2(A+B)=>2C=A+B]
  C=3000-2C
  3C=3000
  C=1000

• a+b+c=3000
  (a+b)+1/2(a+b)=3000
  a+b=3000(2/3)=2000
  2000+c=3000
  c=1000

• given c=(a+b)/2 and a+b+c=3000, so a+b+(a+b)/2=3000, a+b=2000, so c=1000

• A+B+C=3000---(1)
  C=3000-(A+B)---(2)
  By the giving c=1/2(A+B)
  (A+B)/2=3000-(A+B)
  A+B=2000,value substitute in 1
  then c=1000
