I solved this question in less than 10 seconds, I was surprised to find out that it is 95% hard. I probably did something wrong and was lucky to get the correct answer. Please look at what I did and correct me, where I'm wrong.
Since the question stem indicates that the diagram is not drawn to scale, using the provided info, I drew a proper diagram with decent semi-circles.
Instead of using angle YXA as 105°, I turned it upside down and used angle ABY as 105°. Since we are only looking for the ratio of the regions, irrespective of which position the degree is coming from.
Thus,I had the upper shaded region to be 105°, and the lower region to be therefore (360-(180+105)) = 75°.
I went ahead to compute 105/75 = 7/5.
It might seem pretty long but it was pretty fast. Although it seems like a ludicrous luck!

without the addition of a picture,
when an Inscribed Angle like Angle YXA touches the circumference of the circle on the SAME SIDE of the Circle that it is Inscribed upon, then I always like to think of the "Central Angle" as the Reflex Angle.
What I mean is if you draw a Radius from B to A, then you have Angle YBA "Touching" the same 2 Points (Point A and Point Y) as Inscribed Angle YXA does.
The Central Angle that measures the Major Arc from A all the way around the circle to C and then Y will be measured by the Reflex Angle on the Opposite Side of Angle YBA. That Reflex Angle will Equal 2 * (Inscribed Angle of 105 degrees).
If that Reflex Angle = 210 degrees, then the Angle YBA will = 150 degrees because together they are 360 degrees around Point B-Center.
I don't know if this helped anyone. I'll try to draw a picture and get it attached if someone is interested.
