A piece of length 3.532 m is cut from a rod of length 43.4 m. The length of the remaining rod in metre is (up to correct significant figures)
- A 39.9
- B 39.8
- C 39.868
- D 39.87
Answer & Solution
Correct Answer
(A) 39.9
Step-by-step Solution
Detailed explanation
\( \text{Remaining length} = 43.4 \text{ m} - 3.532 \text{ m} = 39.868 \text{ m} \) \( \text{Rounded to one decimal place} = 39.9 \text{ m} \)
