Options

  1. A17.015 and 21.024
  2. B17.014 and 21.023
  3. C17.015 and 21.023
  4. D17.014 and 21.024

Correct answer

D. 17.014 and 21.024

Step-by-step solution

According to the rules for rounding off numbers, if the digit to be dropped is 5 and it is not followed by any non-zero digit, the preceding digit is left unchanged if it is even, and increased by 1 if it is odd. For 17.0145 , the digit to be dropped is 5 . The preceding digit is 4 , which is even. Therefore, it remains unchanged. The rounded number is 17.014 . For 21.0235 , the digit to be dropped is 5 . The preceding digit is 3 , which is odd. Therefore, it is increased by 1 . The rounded number is 21.024 . The r
