Bengaluru and Chennai Slip in India's Dirtiest Cities Rankings; Delhi Ranks Higher Than Mumbai

Imagine a big report card for cities in India that grades them on how clean they are.

This year, Bengaluru, which is famous for computers, and Chennai, a big city, got lower grades and are now considered among the dirtiest.

Even though Delhi is a very busy capital city, it did better than Mumbai in this cleanliness test.

The report shows that even with efforts to keep cities clean, it's still hard to manage trash and keep everything tidy, especially in fast-growing cities.

Some smaller cities, however, are doing a great job and are very clean.

This report helps everyone see where cities need to improve their cleaning and trash systems.
