Question

a+b+c = 14 (a+b):(b+c):(c+a) =6:7:8 then c=?

Answer 1

Let us assume the factor multiplied in ratio is “x”

then it can be written as

a+b= 6x

b+c= 7x

c+a=8x

by adding this three equation ,we get

2(a+b+c)=21*x

now put (a+b+c)=14 (given)

x= 2*14/21 = 4/3

a+b=8

b+c=28/3

c+a=32/3

now solve this three equation ,you will get the result.

Thanks :)
