I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

Spelt forwards I’m what you do every day, spelled backwards I’m something you hate. What am I?

Chhote se Chintu Miyan,
Lambi si Pooch.
Jahan Jaye Chintu Miyan,
Wahan Jaye Pooch.

छोटे से चींटू मियाँ,
लंबी सी पूंछ।
जहाँ जाये चींटू मियाँ,
वहाँ जाये पूंछ।

Bolo kya?

When you say goodbye, I am what you need to tie.
I come as a couple and go wherever you run.

No matter how little or how much you use me, you change me every month. What am I?

When it is alive we sing, when it is dead we clap our hands. What is it?

A finger goes in me. You fiddle with me when you're bored. The best man always has me first. What am I?

There's a day, that comes around once a year.
To celebrate the man, you hold dear.
He gave you life, love and will pick you up if you fall.
When it comes to guys like him, He's the best of all.
Who is he?
