How many times in a given day, minutes and hour clock comes in a straight line ?

Solve The below Equation:

ALFA + BETA + GAMA = DELTA

This was asked in an interview with Coa-Cola.

The interviewer has given me 100 marbles(50 white and 50 black) and two empty boxes.
He then told me that he will leave the room and i need to place all the marbles in two boxes.

And When he come back, he will draw a marble from any of the two box and if the marble is white I will be hired.

Also
* No box can be empty.
* All 100 marbles must be placed in one of the two boxes.

So what should I have done?

In the four images below, can you find the odd one out?

The answer I give is yes, but what I mean is no. What was the question?

A man had five children. He had $100 with him to give to his children. He decided to start with the youngest child and then give $2 more than each younger child to his next elder child.

For example, if he gives $x to the youngest child, he will give $(x+2) to the next one, $[(x+2) + 2] to the next one and so on.

Can you find out how much did the youngest one receive?

Count the number of triangles in the below picture?

There are 2 people near the river and both of them want to get on the other side. The boat can only take one of them. But they got across.
How?
