A woman calls up the police to say that her grandmother’s ring had been stolen.
When they visit her house, they see broken glass on the lawn and dirty footprints. They arrest the woman. Why?
Every dawn begins with me
At dusk I’ll be the first you see
And daybreak couldn’t come without
What midday centers all about
Daises grow from me, I’m told
And when I come, I end all cold
But in the sun I won’t be found
Yet still, each day I’ll be around.
Today is more windy than yesterday, will a return flight take the same time, less time, or the same amount of time to complete?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
Let's do a worked example. Lets say our plane has to travel 300 miles there and 300 miles back. It has a standard cruising speed of 600mph. In the case of no wind it will travel the 600 miles in 1 hour exactly. Simple enough. Let us say that the wind speed is 100mph so the plane will be wind assisted to 700mph and slowed to 500mph - Wind Assisted: 300 miles at 700mph takes 0.429 hours - Wind Slowed: 300 miles at 500mph takes 0.6 hours - Total Time: 1.029 hours
Given two 2s, "plus" can be changed to "times" without changing the results: 2 + 2= 2 x 2.
The solution with three numbers is easy too: 1 + 2 + 3= 1 x 2 x 3.
Now find the answer for 4 numbers and for 5 numbers.
For 4 numbers:
1 + 1 + 2 + 4= 1 x 1 x 2 x 4.
For 5 numbers:
1 + 1 + 1 + 2 + 5= 1 x 1 x 1 x 2 x 4
1 + 1 + 1 + 3 + 3= 1 x 1 x 1 x 2 x 4
1 + 1 +2 + 2 + 2= 1 x 1 x 2 x 2 x 2
The prisoner was locked up in a room with a dirt floor. The room has one window, which is high up above the prisoner's height. The prisoner had a shovel, but he had only 2 days to get out, and digging would take him more than 5. How would he escape?
1 duck saw 4 elephants as it was going toward the river.
Every elephant noticed 2 monkeys going to the river.
Every monkey was carrying 1 dove in its paws.
How many animals are going to the river?
Five animals are moving toward the river.
Here's a detailed answer:
1 duck noticed 4 elephants as it was going toward the river. Hence, 1 animal (the duck) is moving to the river.
The 4 elephants saw 2 monkeys going walking toward the river. Now comes the tricky part. You may think that each elephant saw 2 different monkeys walking toward the river. So you would conclude that 4 x 2 = 8 monkeys were going to the river.
However, the task does not explicitly say that each elephant saw DIFFERENT monkeys. In fact, you can logically infer that the elephants saw the SAME 2 monkeys. Hence, we only have 2 additional animals (monkeys) moving toward the river.
Since every monkey was carrying 1 dove, the 2 monkeys were carrying 2 doves in total.
Summing up, we have 1 duck, 2 monkeys, and 2 doves moving to the river. 1 + 2 + 2 = 5 animals.
What is something you don't own but you can give it to anyone you meet? You only have one, but you can give it away as many times as you want without losing it. What is it?
A group of campers have been on vacation so long, that they've forgotten the day of the week. The following conversation takes place.
Darryl: What's the day? I don't think it is Thursday, Friday or Saturday.
Tracy: Well that doesn't narrow it down much. Yesterday was Sunday.
Melissa: Yesterday wasn't Sunday, tomorrow is Sunday.
Ben: The day after tomorrow is Saturday.
Adrienne: The day before yesterday was Thursday.
Susie: Tomorrow is Saturday.
David: I know that the day after tomorrow is not Friday.
If only one person's statement is true, what day of the week is it?
It is Wednesday. If it was any other day of the week, more than one statement would be true.
To solve the riddle, evaluate each person's statement and write down what day it could be according to the statement.
David's statement indicates it could be any day of the week except for Wednesday. When you list the days that it could be according to everyone's statement, it turns out Wednesday is the day mentioned only one time.
Darryl: Sunday, Monday, Tuesday, or Wednesday
Tracy: Monday
Melissa: Saturday
Ben: Thursday
Adrienne: Saturday
Susie: Friday David: Sunday, Monday, Tuesday, Thursday, Friday or Saturday
