NEETPhysicsUnits and MeasurementMCQ+4 / −1
Taking into account of the significant figures, what is the value of 9.99m−0.0099m9.99 m - 0.0099m9.99m−0.0099m?
  1. A
    9.98 m
  2. B
    9.980 m
  3. C
    9.9 m
  4. D
    9.9801 m
View written solutionFree

Correct answer: A

9.99−0.00999.99 - 0.00999.99−0.0099 = 9.9801 m
Here, 9.98 is having the least number of decimal places of two, so answer should also have only two decimal places. So answer is 9.98 m.
