a+b:b+c:c+a=6:7:8
a+b+c=14
value of c?

• let the ratio be 6x,7x,8x
  (a+b)+(b+c)+(c+a)=6x+7x+8x
  21x=2*14=288
  x=4/3
  a+b=6*4/3=8
  b+c=7*4/3=28/3
  c+a=8*4/3=32/3
  c=a+b+c-(a+b)=14-8=6

• let,
  (A+B)=6k...eq 1
  (B+C)=7k...eq 2
  (C+A)=8k...eq 3
  now,A+B+C=21K/2.......eq 4
  also given A+B+C=14......eq 5
  from eq4 & eq5 we have,
  K=4/3
  solving eq1 & eq4 we have,
  C=(21/2K-6K)=9/2K = 9/2*4/3 = 6
