PHXI02:UNITS AND MEASUREMENTS
367637
Assertion : In addition, result is true upto minimum number of decimal places in any of the numbers involved. Reason : \(1.37+4.0=5.5\) is correct scientifically.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
In addition, the result should be reported with the same number of decimal places as the number with the least decimal places among the numbers. The sum of 1.37 and 4.0 is indeed 5.37. Which upon rounding gives 5.4 . Which upon rounding gives 5.4. So correct option is (3)

Taking into account of the significant figures, what is the value of 9.99 \(m\)-0.0099 \(m\)?
1 \(9.98\,m\)
2 \(9.980\,m\)
3 \(9.9\,m\)
4 \(9.9801\,m\)
Explanation:
In subtration the number of decimal places in the result should be equal to the number of decimal places of that term in the operation which contain lesser number of decimal places. The answer should have three siginificant figures

The area of a rectangular field (in \({m^2}\)) of length 55.3 \(m\) and breadth 25 \(m\) after rounding off the value for correct significant digits is:
1 \(138 \times {10^1}\)
2 \(1382\)
3 \(1382.5\)
4 \(14 \times {10^2}\)
Explanation:
Area \( = \) Length \( \times \) Breadth \( = 55.3 \times 25\) \( = 1382.5 = 14 \times {10^2}\) (\(\because \) Result shall be expressed in 2 significant figures).
