#4 - Money puzzle

I saw a Jeans for Rs97. I dont have enough money , so i borrowed Rs50 from my mom and 50 from my dad = Rs100.
I bought the jeans, and had Rs3 change. I gave dad Rs1 and my mom Rs1 and kept the other Rs1 for myself. Now I owe my mum Rs49 and my dad Rs49. 49+49 = 98 + my Rs1 = 99. Where is the missing Rs1?

Money puzzle

It was only a trick:
I borrowed my parents (Rs50 + Rs50 = Rs100).
I bought the jeans for Rs97 and i had Rs3 change.
So, the money that i borrowed and bought the jeans are Rs100 (borrowing money)
and the change Rs3 also the borrowing money the jeans is Rs97
Total: Rs97 + Rs3(the change) = Rs100
The money that i used to buy the jeans all i borrowed.
Rs97 is the borrowing money, change: Rs3 also the borrowing money. Rs97 + Rs3 = Rs100

#5 - Logic Problem

There is a bag which have 21 blue balls and 23 red balls. You also have 22 red balls outside the bag.

Randomly remove two balls from the bag.
* If they are of different colors, put the blue one back in the bag.
* If they are the same color, take them out and put a red marble back in the bag.

Repeat this until only one marble remains in the bag.


What is the color of the sole marble left in the bag ?

Logic Problem

The last marble will be blue.

Since balls can only be taken out in pairs and you started off with an odd number of blues there is always going to be one blue left over that you'll keep putting back in the box until it's left on it's own.

#9 - 4 Doors Riddle

You are an expert on paranormal activity and have been hired to locate a spirit haunting an old resort hotel. Strong signs indicate that the spirit lies behind one of four doors. The inscriptions on each door read as follows:

Door A: Its behind B or C
Door B: Its behind A or D
Door C: Its in here
Door D: Its not in here

Your psychic powers have told you three of the inscriptions are false, and one is true. Behind which door will you find the spirit?

The spirit lies behind Door D.

If the spirit is behind Door A, then both B and D are true.

If the spirit is behind Door B, then both A and D are true.

If the spirit is behind Door C, then A, C, and D are all true.

If the spirit is behind Door D, then the statements on all the doors are false, except for that on Door B. This matches the rules, and therefore, the resort hotel spirit lurks behind Door D.
