Final answer:
The Mercator projection used in most maps diminishes the size of India, while Africa appears much larger than it actually is.
Step-by-step explanation:
In most maps that use the Mercator projection, the size of India appears smaller than it actually is. This projection distorts the sizes of continents and distances as you move away from the equator. While India is diminished on the map, the size of Africa is actually much larger than it appears. The Mercator projection is known for making Europe and North America look larger than their actual size as well.
