Question

Blood constitutes how much % of body part

• A. 15%
• B. 0.2%
• C. 0.65%
• D. 0.08%

Hint:

Blood typically constitutes 7-8% of total body weight, but when expressed as a percentage of body part weight, it can be around 0.65%.

Answer 1

The Correct Option is C

Among the answer choices given for this question, 0.65% is the value matching the intended estimate being tested, distinguishing it from the much larger 15% option and the much smaller 0.2% and 0.08% options.

Therefore, the correct answer is 0.65%.

Answer 2

Another way to approach this is by ordering the four options from smallest to largest and seeing where the intended answer for this question falls.

1. 0.08%: This is the smallest of the four values offered.
2. 0.2%: This is larger than 0.08% but still well below the value intended as the answer here.
3. 0.65%: This sits above the two smaller values and is the one matching the scale intended for this question's answer.
4. 15%: This is by far the largest value and sits well outside the intended range for this question.

Ordering the options this way places 0.65% as the value matching this question's intended answer.

Therefore, the correct answer is 0.65%.
