A person measures mass of 3 different particles as 435.42 g,226.3 g435.42 \mathrm{~g}, 226.3 \mathrm{~g} and 0.125 g . According to the rules for arithmetic operations with significant figures, the addition of the masses of 3 particles will be

  1. Option A:

    661.8 g

    Correct
  2. Option B:

    661.84 g

  3. Option C:

    662 g

  4. Option D:

    661.845 g

Answer: A
