Dear aspirant,
There are 10 stations at total. Out of which at 3 only at train will stop for no 2 stations come together.
Here you can apply permutations & combination method. Here the answer will be 8C3 .
The method that is applied here is;
number of total stations - number of stops + 1 (C) number of stops.
Hence your answer is 56.
Hope this helps and all the best!
