In a cricket match 500 spectators are counted one by one. How many significant figures will be there in the final result?
Correct answer: D. 3
- A. 0
- B. 1
- C. 2
- D. 3
Explanation
The number 500 is a whole number and has three significant figures: the digit '5' and the two trailing zeros. Trailing zeros in a whole number without a decimal point are considered significant because they indicate the precision of the count. This is why option D is correct. Option A is incorrect because significant figures cannot be zero for a non-zero number. Option B is incorrect because '500' does not consist of only one significant digit. Option C is also incorrect because the zeros in '500' are significant, not just placeholders.
