MAH-CET 2025 — Reasoning PYQ

In a small town, there are types of vehicles: cars, bikes, and buses. The town council recently conducted a survey to understand the usage of these vehicles. The data showed that 50% of the population owns cars, 30% own bikes, and 20% use buses as their primary mode of transportation. Additionally the survey revealted that 40% of car owners also own bikes, while only 10% of bike owners also use buses. The council plans to introduce incentives to promote bus usage.

If the council introduces a policy offering free bus passes to 30% of the population, and all these individuals start using buses exclusively. what percentage of the population would now rely on buses?
