In the drawer beside your bed, you have three orange, two pink and five purple balls. There is no electricity and the room is completely dark. How many balls you must take out to make sure you have one ball of each color at least.
9
2 < 3 < 5
To find out the required number of balls, take one in place of the least number (i.e. take one pink ball) and then add all the greater numbers (i.e. three orange and five purple balls) to it.
Required number of balls = 1 + 3 + 5 = 9.

Suppose "s" represents the number of seconds in a day and "h" represents the number of hours in ten years (which will also include two leap years), can you calculate which quantity is greater from the two variables?
S = 60 * 60 * 24 seconds = 86, 400 seconds.
H = (8 * 365 *24) + (2 * 366 *24) hours = 87, 648 hours
Clearly, H is greater than S even though not by much.
Can you count number of squares in a figure below ?
30 squares.
Assuming smallest square side is 1 cm, then
Total number of squares with side 1 cm: 16
Total number of squares with side 2 cm: 9
Total number of squares with side 3 cm: 4
Total number of squares with side 4 cm: 1
Adding 16+9+4+1 = 30
A man has four playing cards in random order in his hand ( 6 7 8 and 9)
He desires them placed in ascending order from his left to his right.
* To do this, he pulls the left card (from your perspective) and puts it end.
* He then takes the third card from the right (from your perspective) and puts it in end.
Can you guess the original order of the cards ?
6 8 9 7 (user perspective)
7 9 8 6 (from his perspective)
Detail:
From user perspective:
6 8 9 7 => 8 9 7 6 => 9 8 7 6
For his perspective
6 7 8 9 (ascending order as desired)
In a secret society, a buried chamber can be accessed only via a secret password. The password is seven characters long and comprises of just letters and numbers.
You find a code that can help you in cracking the password. The code says "You force heaven to be empty".

If one and a half boys, eat one and a half burgers in one and a half hours.
How many burgers can 9 boys eat in 3 hours ?
18
More hours => more burgers.
More boys => more burgers.
The time become twice (3 hours / 1.5 hours).
Boys become six times (9 / 1.5).
Number of burgers = 2 * 6 * Original(1.5)
= 18
Alpha and Beta have same amount of petrol in their respective cars. Alpha can drive for 4 hours whereas Beta can drive for 5 hours with the amount of petrol left.
Both of them start driving at the same time. After a few hours, they find out that the amount of petrol remaining in one of the cars is four times the other car.
Can you calculate for how long did they drive the cars?
3 3/4 hours
Assume that the initial amount of petrol in each of the petrol tanks be P.
Now, let us assume that they drove for H hours.
In that case, the amount of petrol used by one car in H hours will be = P*H /4
The amount of petrol used by the other car will be = P*H/5
Therefore, the petrol left in one car = P - P*H / 4
Petrol left in the other car = P - P*H / 5
Now, according to the question,
P - P*H / 5 = 4 (P - P*H / 4)
=> H = 15 / 4 = 3 3/4 hours.
