What type of error is writing India's area as (32.8) million sq km?

Answer and explanation

Correct answer: Decimal place error

The direct answer is A, decimal-place error. India's area is approximately 3.28 million square kilometres, not 32.8 million square kilometres. Compare the numbers carefully: 3.28 has two digits after the decimal, whereas 32.8 has the decimal shifted one place to the right. Since 32.8 is ten times 3.28, the written value greatly exaggerates India's area. Option A is correct because the mistake is in the position of the decimal point. Option B, correct coastline calculation, is unrelated: the statement concerns area, not coastline. Option C, correct rank identification, is unrelated and does not repair a numerical error. Option D, correct unit of land boundary, is also unrelated; a boundary is a length, while the given quantity is area. Memory trick: first check the unit, then check the decimal position.
