A train normally takes $4$ hours to run between the stations A and B. One day, the train started from station A but after one hour its speed went down to half of its normal speed, due to heavy rain. Having travelled $100$ kms in the heavy rain, the train's driver could not see the railway track due to water flowing on it, so he decided to further slow down the speed by $50\%$. After that, the train reached at staion B in another $4$ hours. Which of the following is the time taken by the train to reach at station B from station A on that particular day ?

Two equations are given. You have to solve these equations and select the alternative which depicts the correct relationship between $X$ and $Y$.

I. $14X^2-41X+15=0$

II. $14Y^2+29Y-15=0$

Two equations are given, you have to solve these equations and find out the values and get the answer

$$\begin{gathered} \left(i\right) 17X^2+48X=9 \\ \left(ii\right) 13Y^2=32Y-12 \end{gathered}$$
