If $$\frac{{b - c}}{a}$$+ $$\frac{{a + c}}{b}$$+ $$\frac{{a - b}}{c}$$= 1 and a - b + c ≠ 0 then which one of the following relations is true ?

$\frac{1}{b} = \frac{1}{a} - \frac{1}{c}$$

$\frac{1}{c} = \frac{1}{a} + \frac{1}{b}$$

$\frac{1}{a} = \frac{1}{b} + \frac{1}{c}$$

$\frac{1}{b} = \frac{1}{a} + \frac{1}{c}$$

If $$\frac{{b - c}}{a}$$+ $$\frac{{a + c}}{b}$$+ $$\frac{{a - b}}{c}$$

1.	If $$\frac{{b - c}}{a}$$+ $$\frac{{a + c}}{b}$$+ $$\frac{{a - b}}{c}$$= 1 and a - b + c ≠ 0 then which one of the following relations is true ?
A.	$\frac{1}{c} = \frac{1}{a} + \frac{1}{b}$$
B.	$\frac{1}{a} = \frac{1}{b} + \frac{1}{c}$$
C.	$\frac{1}{b} = \frac{1}{a} - \frac{1}{c}$$
D.	$\frac{1}{b} = \frac{1}{a} + \frac{1}{c}$$
Answer» C. $\frac{1}{b} = \frac{1}{a} - \frac{1}{c}$$
