Percentage change (rise/fall) in the production of Company $Y$ in comparison to the previous year, for different years are:

For 1997,

$=\left[\dfrac{35 - 25}{ 25} × 100\right]\%$

$= 40\%.$

For 1998,

$=\left[\dfrac{35 - 35}{ 25} × 100\right]\%$

$= 0\%.$

For 1999,

$=\left[\dfrac{40 - 35}{ 35} × 100\right]\%$

$= 14.29\%.$

For 2000,

$=\left[\dfrac{50 - 40}{ 40} × 100\right]\%$

$= 25\%$

Hence, the maximum percentage rise/fall in the production of Company $Y$ is for 1997
