If a1 - 2a + b1 - 2b + c1 - 2c = 1/2 , then the value of 11 - 2a + 11 - 2b + 11 - 2c is?

Answer: Option D

$$\begin{array}{rl}& \frac{a}{1-2a}+\frac{b}{1-2b}+\frac{c}{1-2c}=\frac{1}{2}\\ & \text{Multiply by 2 both side}\\ & \Rightarrow \frac{2a}{1-2a}+\frac{2b}{1-2b}+\frac{2c}{1-2c}=1\\ & \text{Adding 3 both side}\end{array}$$
$$\Rightarrow 1+\frac{2a}{1-2a}+1+\frac{2b}{1-2b}+1+$$       $$\frac{2c}{1-2c}=$$  $$1+3$$
$$\Rightarrow \frac{1}{1-2a}+\frac{1}{1-2b}+\frac{1}{1-2c}=4$$
