Question

If (a+b):(b+c):(c+a) = 5:6:9 and a+b+c=10,
what is the value of c?
3
4
5
6​

Answer 1

Answer:

C = 5

Step-by-step explanation:

Let, a+b = 5------------(1)

b+c = 6------------(2)

c+a = 9------------(3)

NOW,

a+b+c = 10

c = 10 - (a+b)

= 10 - 5 [FROM EQUATION------(1)]

= 5

And we can check by finding the values of 'a' and 'b'. i.e., {a = 4}, {b = 1}

So, a+b+c would always be equal to 10
