Two trains 'A' and 'B' of length 'lll' and '4l4 l4l' are travelling into a tunnel of length 'L\mathrm{L}L' in parallel tracks from opposite directions with velocities 108 km/h108 \mathrm{~km} / \mathrm{h}108 km/h and 72 km/h72 \mathrm{~km} / \mathrm{h}72 km/h, respectively. If train 'A' takes 35 s35 \mathrm{~s}35 s less time than train 'B' to cross the tunnel then. length 'LLL' of tunnel is : (Given L=60l\mathrm{L}=60 lL=60l )
