Answer:
The answer is: 20
Explanation:
Significant figures are the meaningful digits that contribute to the precision and accuracy of the given number.
The given number: 24.67 has four significant figures because all the non-zero digits are significant.
Rounding off refers to the method of expressing the given number to the nearest whole number or nearest thousand, hundred, ten, etc.
Now, rounding off the given number (24.67) to one significant figure gives 20, which has only one significant figure. As the trailing zero is not significant.
