If (a+b):(b+c):(c+a)= 2:3:3 and (a+b+c)= 16, then the value of c is:

Options
- 5
- 6
- 7
- 8

CORRECT ANSWER : 8

Discussion Board
i guess c should be 6 not 8

a+b=4
b+c=6
c+a=6
now 2(a+b+c)=16
a+b+c=8
a+b=2
after subtracting we get
c=6 , not 8 in this question should''t be mention (a+b+c)=16

Aptitude

Given a:b:c=2:3:3
Let a=2x,b=3x,c=3x
Given a+b+c=16
2x+3x+3x=16
8x=16, x=2
Therefore a=2*2=4,b=3*2=6,c=3*2=6

Solution

given:
a+b = 2 --->a=(2-b)
b+c =3 ---> c=(3-b)

c+a=3
(3-b)+(2-b) = 3
b=1;

similarly,
a=1
c=2;

given (a+b+c) = 16
1K+1K+2K=16
4K=16
K=4

c=2K=2(4) =8
