Production of company D = 2700
Production of company A = 1500
$$\eqalign{
& h = \frac{\text{Production of company D}}{\text{Production of company A}} \cr
& h = \frac{2700}{1500} \cr
& h = \frac{9}{5} \cr
& h = 1.8 \cr} $$
2.
The ratio of the number of companies having more demand to those having more production than demand is -
Given $$x$$% of demand for company C = Demand for company B
$$\eqalign{
& \Rightarrow \frac{2500\times x}{100} = 600 \cr
& \Rightarrow 25x = 600 \cr
& \Rightarrow x = \frac{600}{25} \cr
& \Rightarrow x = 24 \cr} $$
