In order to find the approximate value of $$sqrt{1000}+frac{3.001}{4.987} of 1891.992$$, let us find the approximate value of $$frac{3.001}{4.987} of 1891.992$$ first. We can approximate $$4.987 approx 5$$ and $$3.001 approx 3$$ and $$1891.992 approx 1900$$ So, the approximation looks like $$frac{3}{5} imes 1900 = 3 imes 380 = 1140$$ The approximate value of $$sqrt{1000} = 32$$ Hence, the final answer will be close to $$1140+32 = 1172 approx 1170$$
