GATE 2021 Chemical Engineering Question 63: Second Order System Step Response and Overshoot Calculation

A process has a transfer function G(s)=Y(s)/X(s)=(20)/(9000s²+240s+1). Initially the process is at steady state with x(t=0)=0.4 and y(t=0)=100. If a step change in x is given from 0.4 to 0. 5, the maximum value of y that will be observed before it reaches the new steady state is _______ (round off to 1 decimal place).
