Given,
u=36km/h.= 36000m/3600s
=10m/s
t=80s
length of bridge=600m
Let's the length of train be x.
Since ,
Velocity= distance(l)/time
10 = 600+x/ 80
800 =600+x
x =800-600
= 200m.
Thank you!

Explanation:
u - 36km/hr
u in metre per second
10 m/sec
time(t)-- 80s
Length of bridge -- 600m
Let the length of train be x
Velocity -- distance/time (distance by time)
Velocity --10m/s
distance --600+x
10 equal to 600+x by 80
800 equal to 600+x
therefore, X-- 800-600
200m
