Let's try an approach that relies on the working population and commuting habits.

Estimate the working population in Bangalore

Bangalore has a population of approximately 12 million. If we consider about 30% of them to be in the working age and employed, that's about 3.6 million people.

Consider the proportion of workers who use Ola

Not all workers would use Ola; many would use personal vehicles, other cab services, public transportation, or non-motorized transport. If we assume that 15% of workers use Ola for their commute, we get about 540,000 Ola users.

Factor in commute frequency

Most workers commute twice a day - from home to work and back. However, not everyone would use Ola for both trips. If we assume on average, these Ola users take 1.2 rides per day (factoring in those who take just one ride and those who use Ola for other trips as well), we'd get around 648,000 rides.

Account for non-work rides

The calculation so far has focused on work-related rides, but Ola is used for non-work trips too: shopping, social visits, etc. To account for these, let's assume that the number of non-work rides is about 20% of work-related rides. That gives us another 130,000 rides (20% of 648,000).

Adding work-related and non-work rides, the total estimated number of Ola rides taken in Bangalore on a daily basis is around 778,000.
