The following questions are extracted from the NCERT Class 8 Mathematics textbook "Ganita Prakash", Chapter 7, "Proportional Reasoning-1". These include in-text questions and examples presented as questions. Due to the inability to directly parse the official PDF for end-of-chapter exercises and the strict requirement to only use questions verifiable from the specified PDF, only the in-text questions with verifiable wording are provided here. Questions requiring diagrams or incomplete wording from the search snippets have been omitted.

Answer: The width of image D (90 mm) changes by a factor of 90/60 = 3/2 compared to image A (60 mm). The height of image D (60 mm) changes by a factor of 60/40 = 3/2 compared to image A (40 mm). Yes, the factors are the same (3/2).

- Identify the given dimensions for Image A and Image D. (Assuming Image A: width = 60 mm, height = 40 mm; Image D: width = 90 mm, height = 60 mm, as implied by search results).
- Calculate the factor by which the width of Image D changes compared to Image A: Factor for width = (Width of Image D) / (Width of Image A).
- Calculate the factor by which the height of Image D changes compared to Image A: Factor for height = (Height of Image D) / (Height of Image A).
- Compare the two factors to determine if they are the same.
