ok 6 is not b so i think is a?
and 20 if its 25-30% its b?
To determine the answer to your first question, you mentioned that 6 is not b. Since the options given are a and b, and you have ruled out b, then a would be the correct answer.
Regarding your second question, you stated that if 20 is between 25-30%, the answer would be b. However, it's important to note that 20 is actually not between 25-30% since 20 is less than both 25 and 30. As a result, the correct answer may not be option b.
Please check the available options again to ensure the correct answer based on the given information. If you need further assistance, feel free to provide more details or context.
