Answer 2

Answer:

6 routes

Step-by-step explanation:

Case 1: Going via sea first

Imagine that you have started your journey from Goa and have reached Mumbai via sea route. Then after reaching Mumbai, there would be three different routes from there to Delhi. Since all these routes [between Mumbai and Delhi] are different, let us name them as routes A,B and C respectively.

Now, come back to Mumbai sea port. We have reached Mumbai by sea now and we can take any one of the three routes to Delhi from there. So, each route is counted as each possibility. Since there are 3 routes, there are 3 kinds of possibilities. They are:

1. Goa-------> Mumbai----------->Delhi (via route A)
2. Goa-------> Mumbai----------->Delhi (via route B)
3. Goa-------> Mumbai----------->Delhi (via route C)

Case 2: Going via air

Similarly, you can also travel to Mumbai from Goa via an aeroplane and, in turn, again travel by any of the three routes to reach Delhi. Thus , here too, there are 3 possible routes.

Combining Cases 1 and 2,

There are a total of 6 possible routes possible from Goa to Delhi via Mumbai.
