The significant figures in 1.0024,1.2401.0024,1.240 and 0.0020 are respectively

Options

  1. A5,4,25,4,2
  2. B3,3,13,3,1
  3. C5,3,45,3,4
  4. D5,3,25,3,2

Correct answer

A. 5,4,25,4,2

Step-by-step solution

In 1.0024 , all figures are significant. In 1.240 ,the significant figures are four (zero tells about precision). Zero before a number are not significant, hence 0.0020 has only two significant numbers (2 and 0 after 2).
