Question

a+b:b+c:c+a=4:5:6 then a:b:c

Answer 1

2(a+b+c)=15  (4+5+6)

a+b+c=7.5

a=a+b+c)-b+c

a=7.5-5=2.5

b=7.5-6=1.5

c=7.5-4=3.5

all are satisfied

Answer 2

Answer:

∴  A : B : C = 5 : 3 : 7

Step-by-step explanation:

Hey Mate,

Given Data,

( a + b ) : ( b + c ) : ( c + a ) = 4 : 5 : 6

∴ a + b + b + c + c + a = ( 4x + 5x + 6x )

2 ( a + b + c ) = 15x

a + b + c = 7.5x

So,

A = 7.5x - 5x = 2.5x

B = 7.5x - 6x = 1.5x

C = 7.5x - 4x = 3.5x

Suppose ,

X = 2

So,

A = 5

B = 3

C = 7

∴  A : B : C = 5 : 3 : 7
