A. 3x-2y=0
B. 2x=y
C. x+y=3y
D. 4x-3y=3x
E. None of these

After brain storming over this question for 3 mins, I decided to Take initial cost as 100, x = 100
A. 3x-2y=0 => 3x=2y
B. 2x=y => This case is not possible, since the value is depreciating, how can the final value be greater than initial value- Eliminated this
C. x+y=3y => x = 2y
D. 4x-3y=3x => x= 3y

x = 100, Depreciation = D
D1 for 20% , Value of x after D1 = 80
D2 for 50/3 %, Value of x after D2 = 67
D3 for 25%, Value of x after D3 = 51,which is the value for y

x= 2y
This is in line with Option C

Correct Answer C

the awkward part is to translate this : 50/3 % = $$(\frac{50}{3})/100 = \frac{50}{300}$$

$$x * (\frac{100}{100}-\frac{20}{100})(\frac{300}{300}-\frac{50}{300})(\frac{100}{100}-\frac{25}{100}) = y$$

$$x * \frac{4}{5}*\frac{5}{6}*\frac{3}{4} = y$$

$$x * \frac{1}{2} = y$$

$$x = 2y$$

$$x + y = 3y$$

so C

Question was pretty simple.
The answer choices were quite messed up
The equation simplifies to:
$$(4*5*3)/(5*6*4)*x=y$$
$$1/2x= y$$
therefor x= 2y
hence answer C
