If a+b : b+c : c+a = 6:7:8 and a+b+c = 14, then the value of c is

a. 6
b. 7
c. 8
d. 14
e. None of These

• a+b=6x,b+c=7x,c+a=8x by adding these equations,we get 2(a+b+c)=21x since a+b+c=14
  therefore we get x=4/3 by solving c=6.

• ans is [a] 6
  let a+b=6x
  b+c=7x
  c+a=8x
  2(a+b+c)=21x
  28=21x
  x=28/21
  now a+b+c=14
  so 6x+c=14
  c=14-(6*28/21)
  c=14-8
  c=6

• a+b= 6x,b+c=7x,c+d=8x
  =2(a+b+c)=21x,and given a+b+c=14
  so x=4/3 now solving all eqn we get c=6
