Question

Which measuring tool is used in the given image? What is the combined length of the paper clip and the key?

• A. Measuring tape, 11 inches
• B. Measuring tape, 7 inches
• C. Inch scale, 5 inches
• D. Inch scale, 9 inches

Answer 1

The correct option is C Inch scale, 5 inches

$\text{Say:}$
$\bullet$ Here, the measuring tool or measuring scale used has only inch marks on it.

$\bullet$ So, an inch scale is used here.

$\bullet$ Now, let us first find out the length of the paper clip and key individually to get the answer.

$\text{Steps:}$
$\bullet$ The paper clip starts from 0 inches and ends at 2 inches.

$\bullet$ So, the length of the paper clip is 2 inches.

$\bullet$ The key starts from 6 inches and ends at 9 inches.

$\bullet$ So, the length of the key = 9 - 6 = 3 inches.

$\bullet$ The combined length of both the objects = 2 + 3 = 5 inches.

$\bullet$ Hence, option C is the correct answer.

$\text{Probing/ error analysis question:}$If both the paper clip and the key are placed one after the other without any gap starting from the 0 inches mark, where will the end point be?
A: Since the combined length of the paper clip and the key is 5 inches, the end point will be at the 5 inches mark.
