@Aditya.
15%+55% = 70,

12750÷ 30 = 425*70 = 29750 + 12750 = 42500ans.

Train of length = x.
Speed of train is 60km/hr.
1km is 1000 * 60 =60000.
1hr is 60 minutes * 1hr =3600.
60000 ÷ 3600=16.6667.
Said that 9sec crosses a pole ,then
X = 16.667 * 9sec = 150m.
Distance = speed * time.
Speed of train is 60km/hr.
1km is 1000 * 60 =60000.
1hr is 60 minutes * 1hr =3600.
60000 ÷ 3600=16.6667.
Said that 9sec crosses a pole ,then
X = 16.667 * 9sec = 150m.
Distance = speed * time.
