From the figure, we can say that x+y=180;
Since, x is (3/8)*(x+y)
x = (3/8) * 180
x = 67.5.

Ans is (B).

(E) 112.5



From the equation 5x = 3y and from the figure x + y =100
Instead of solving the equation, we can divide 100 into 8 parts and assign 5 parts to y and 3 parts of x.
so x = 3*100/8 = 67.5 - option B)

From the diagram given, its clear that x should be less than 90 & its value has to be in decimal (\(\frac{180}{8}\) would not provide an integer)

Only 67.5 fits in

Answer = B

I doubt that the GMAT diagrams are to scale. Kaplan says never take the diagram to scale unless specified.
I think your approach here might not be the best one.

OFFICIAL GUIDE:

Problem Solving
Figures: All figures accompanying problem solving questions are intended to provide information useful in solving the problems. Figures are drawn as accurately as possible. Exceptions will be clearly noted. Lines shown as straight are straight, and lines that appear jagged are also straight. The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero. All figures lie in a plane unless otherwise indicated.

Data Sufficiency:
Figures:
Figures conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).
• Lines shown as straight are straight, and lines that appear jagged are also straight.
• The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero.
• All figures lie in a plane unless otherwise indicated.

from the figure, (x + y) = 180

i.e. x/(x + y) = 3/8
i.e. x/180 = 3/8

i.e. x = 67.5

Answer: option B

Since we have two supplementary angles, x + y = 180. Thus, we can replace (x + y) with 180 in the equation and solve for x:

x/(x + y) = 3/8

x/180 = 3/8

8x = 540

x = 67.5

Answer: B
