Consider Amit lives in Delhi,connected to the internet via a $100 \hspace{0.1cm}Mbps$ connection retrieves a $250 \hspace{0.1cm} KB$ webpage from server in Bangalore, where page contain $3$ images of $500 \hspace{0.1cm} KB$ each.Assume one way propagation delay is $75 \hspace{0.1cm} ms$ and Amit's access link is the bandwidth bottleneck for this connection.If $T1$ is the time taken for the page with the images to appear on Amit's screen using nonpersistent $HTTP$ and $T2$ is time using persistent connection then $T=T1-T2$ will be ......msec. (Assuming queuing delay is zero)
