If 20% of (A + B) = 50% of B, then value of $$\frac{2A - B}{2A + B}$$   is :

A. $$\frac{1}{2}$$

B. $$\frac{1}{3}$$

C. $$\frac{1}{41}$$

D. 1

Answer: Option A

Solution(By Examveda Team)

$$\frac{20}{100}$$ (A + B) = $$\frac{50}{100}$$ (B)
2A + 2B = 5B
2A = 3B
A = $$\frac{3}{2}$$ put value of A in given equation
$$\frac{2A - B}{2A + B}$$
= $$\frac{3B - B}{3B + B}$$
= $$\frac{2B}{4B}$$
= $$\frac{1}{2}$$
