Question: The length of a rod is measured as 50 cm with an error of 1 cm. What is the minimum possible length?
Options:
49 cm
50 cm
51 cm
48 cm
Correct Answer: 49 cm
Solution:
Minimum possible length = Measured value - Error = 50 - 1 = 49 cm.

Questions & Step-by-Step Solutions
The length of a rod is measured as 50 cm with an error of 1 cm. What is the minimum possible length?
Step 1: Identify the measured length of the rod, which is 50 cm.
Step 2: Identify the error in the measurement, which is 1 cm.
Step 3: To find the minimum possible length, subtract the error from the measured length.
Step 4: Perform the calculation: 50 cm (measured length) - 1 cm (error) = 49 cm.
Step 5: Conclude that the minimum possible length of the rod is 49 cm.
