# A bee of mass 0.000087 Kg sits on a flower of mass 0.0123 Kg. What is the total mass supported by the stem of the flower up to the approximate significant figures?

The mass of the bee is accurate up to the sixth decimal place, but the mass of the flower is accurate only up to the fourth decimal point.
Hence the sum (0.000087+0.0123) needs to be rounded off to the fourth decimal point also.
Therefore the answer is 0.0124 Kg.
