Explanation:

We need to first go from Chennai → Bangalore.

There are 2 different trains, 3 different flights & 5 different bus services to travel from Chennai to Bangalore.

Out of 10 ways we need to choose 1 i.e., ¹⁰C₁ = 10 ways.

Now, need to from Bangalore. → Bhopal

There are 5 different trains, 6 different flights & 7 different bus services to travel from Bangalore to Bhopal.

Out of 18 ways we need to choose 1 i.e., ¹⁸C₁ = 18 ways.

∴ Total number of ways to go from Chennai → Bangalore → Bhopal = 10 × 18 = 180 ways.

Hence, 180.
