Rishi walks south for 2 km from home,

Then west for 3 km

If Santa gives Banta $12 they will both have the same amount of money.

Who has what?

Three boxes are all labeled incorrectly, and you must get the labels right.
The labels on the boxes read as follows:

Box 1: nails

Box 2: screws

Box 3: nails and screws

To gain the information you need to move the labels to the correct boxes, you may remove a single item from one of the boxes. You may not look into the boxes, nor pick them up and shake them, etc.

Can this be done? If so, how? If not, why not?

Find out the highest possible number from image by moving only 2 match stick.

500 at the beginning, 500 at the end,
5 in the middle is seen,
The first of all letters, the first of all figures
Take up their stations between,
String them all together, and you will see
The name of an ancient king.

My bath has two taps and a plug hole - and a leak!

The cold tap on its own fills the bath in 20 minutes, the hot one in 30 minutes.

The plug hole can drain the bath in 16 minutes with the taps off.

The leak would empty a full bath in 2 hours.

How long will the bath take to fill if I leave both taps on with the plug left out?
