GRE General TestQuantitative ReasoningMedium
A photography studio is resizing an image. The original image has dimensions of 1200 pixels by 800 pixels. If they want to resize it so that the longer side is 1500 pixels, what will be the length of the shorter side to maintain the aspect ratio?
- A900 pixels
- B1200 pixels
- C1000 pixels
- D1125 pixels
Show answer & explanationAnswer & explanation
Correct answer: C. 1000 pixels
Maintain the aspect ratio by setting up a proportion: (original longer side) / (original shorter side) = (new longer side) / (new shorter side).
Why the other options are wrong
- A. This would be the result if the original ratio was 4:3 and the new long side was 1200 (1200/4*3=900).
- B. This would imply the shorter side remains unchanged while the longer side increases, distorting the aspect ratio.
- D. This might be a result of an incorrect ratio or calculation.
Aspect Ratio Scaling
Aspect ratio scaling involves resizing an image or object while preserving the proportional relationship between its width and height.
- Ratio of width to height remains constant.
- Used to avoid distortion when resizing.
- Often solved using proportions.
Memory trick: Aspect's Always Proportional: Set up your ratios carefully, then cross-multiply for the missing piece.
