Solution
The question is asking to match the numbers in List - I with the number of significant figures they have in List - II.
Significant figures are the digits in a number that carry meaningful information about its precision.
Here's how to count them:
- Non-zero digits are always significant.
- Any zeros between significant digits are significant.
- Leading zeros are not significant. They're only placeholders.
- Trailing zeros in a number containing a decimal point are significant.
Let's count the significant figures for each number:
(A) 1001 - This number has four non-zero digits, so it has 4 significant figures. So, (A)-(II).
(B) 010.1 - This number has three significant figures. The leading zero is not significant, but the other three digits are. So, (B)-(I).
(C) 100.100 - This number has six significant figures. The trailing zeros after the decimal point are significant. So, (C)-(IV).
(D) 0.0010010 - This number has five significant figures. The leading zeros are not significant, but the trailing zero after the last non-zero digit is. So, (D)-(III).
So, the correct answer is (A)-(II), (B)-(I), (C)-(IV), (D)-(III).
