Question 69

---

If we want to resize a 1024 x 768 pixels image to one that is 640 pixels wide with the same aspect ratio, what would be the height of the resized image?

1. 1. 420 Pixels
2. 2. 460 Pixels
3. 3. 480 Pixels
4. 4. 540 Pixels

Answer : 3. 480 Pixels

Explanation

Aspect Ratio of Image = Width / Height

Aspect ratio of 1024 × 768 pixels image = 1024/768 = 4/3

∴ Aspect ratio of modified pixels image = 4 / 3 = 640 / height(new)
∴ 4/3 = 640/Height
∴ Height = (3*640)/4
∴ Height = 480 Pixels

So, option 3 is correct answer
