Answer
Explanation
Number of candidates failing from city $D$ $$\begin{aligned} & =\left(\frac{3}{4} \times 2.27 \times 100000\right) \\ & =\left(\frac{3}{4} \times \frac{227}{100} \times 100000\right)=(227 \times 750) \end{aligned}$$ Number of candidates failing from city $A$ $$\begin{aligned} & =\left(\frac{3}{10} \times 1.25 \times 100000\right) \\ & =\left(\frac{3}{10} \times \frac{125}{100} \times 100000\right)=(300 \times 125) \end{aligned} \text { Required ratio }=\frac{227 \times 750}{300 \times 125}=\frac{227}{50}=227: 50 .$$
