Question:

If (a + b) : (b + c) : (c + a) = 5 : 7 : 4 and a + b + c = 32 then the value of c is :

Options:

Correct Answer:

Explanation:

(a + b) : (b + c) : (c + a) = 5 : 7 : 4

2(a + b + c) = 16x

a + b + c = 8x = 32

x = \(\frac{32}{8}\) = 4

Now,

⇒ (a + b + c) - (a + b) = 32 - 5x = 32 - 20 = 12

⇒ c = 12
