I didn't have barrons in front of me so I couldn't go through looking at the answer choices and eliminating choices, but from the top view in the picture, I can see how that would be correct.
I started by looking at the front view. That rectangular object on near the top right could signify a few things:
1. It could be a rectangular solid coming out at you.
2. It could be a rectangular solid cut out from the object.
3. It could be a triangular solid coming out at you and angled towards you and to the right.
4. It could be a triangular solid coming out at you and angled towards you and to the left.
5. It could be a triangular solid cut out from the object and angled away from you to the right.
6. It could be a triangular solid cut out from the object and angled away from you and to the left.
7. It could be a semi-circular solid coming out at you.
8. It could be a semi-circular solid cut out from the solid.
I guess I could have saved some time and just said anything that would only produce a line at each end, oh well.
We can eliminate all options where the object comes out at you because the side view shows the top and bottom halves even.
We can also eliminate choice 2 because there are no vertical lines in the side view to indicate only part of the top right us removed. If all of the top right of the object were removed we wouldn't see a horizontal line on the top right of the front view.
Now we are looking at answer choices for rectangular shaped object (from the width of both front and side views) with a circle or triangle cut out from the right 2/3.
We are also looking for a line that would indicate the boundary of the slope on the left and the flat top. We know the slope is continuous along the entire width of the object (by width i mean top to bottom looking at top view) because there are no dotted lines indicating something cut out of it. Without the answer choices I can't go into any more about eliminating choices, but what I've said so far might do it.
This process goes so much quicker when its in your head rather than being written or read.
Hope that helps.
