MONEY AND POWER

 

What would come next in the sequence below? The title is a hint.

 

$0.16

$0.15

$3.20

$0.25

$17.50

$1.00

$6.00

$80.00

N/A

$140.00

     ?

 

Answer:

 

$900

 

Beginning with the smallest value of US currency (the penny), the value of each coin or bill is multiplied by the number of the president who appears on it. 

 

Lincoln is on the penny and was the 16th president - 16 x $0.01 = $0.16

 

Jefferson is on the nickel and was the 3rd president - 3 x $0.05 = $0.15

 

Roosevelt - dime - 32 x $0.10 = $3.20 

Washington - quarter - 1 x $0.25 = $0.25

Kennedy - half dollar - 35 x $0.50 = $17.50 

Washington - one-dollar bill - 1 x $1.00 - $1.00

Jefferson - two-dollar bill - 3 x $2.00 = $6.00

Lincoln - five-dollar bill - 16 x $5.00 = $80.00 

Hamilton - ten-dollar bill - never president = N/A 

Jackson - twenty-dollar bill - 7 x $20.00 = $140.00

GRANT - fifty-dollar bill - 18 x $50.00 = $900.00 

 

Q:What comes after $900?

What is the arithmetic average of the first one million odd numbers?

 

 Answer:

 

1,000,000 - The average of the first n odd numbers is always n, the number of odd numbers.

 

For example, 1 + 3 + 5 = 15 (average 3)

                        1 + 3 + 5 + 7 = 16 (average 4) 

DAY 479

If .......

9 + 3 = 15

9 + 7 = 47

8 + 5 = ? 

HINT:

The + sign may or may not mean plus.

Answer:

 

8 + 5 = 27

 

Explanation:

Multiply the two given numbers, then subtract their sum:

 

9 X 3 = 27

27 - 12 = 15, etc.

 DAY 478

There are only 10 kinds of people: those who understand binary numbers, and those who don't.

Musical Limerick

Jon Saxton

In Colossal Book of Word Play

Martin Gardner

 

A dozen, a gross, and a score,

Plus three times the square root of four,

Divided by seven,

Plus five times eleven,

Is nine squared and not a bit more.*

 

*This limerick can be written out numerically as a correct equation, beginning with 12 + 144 + 20 and ending with 9 (squared) + 0.

 

 

DAY 476

 

From Brainteasers and Mind Benders 

Ben Hamilton

Use all the digits 0 - 9 to make two sums and one product.

HINT:
The product uses four digits.

Answer:

 

7 + 1 = 8

9 - 6 = 3

4 x 5 = 20

 DAY 475

A man went into a bank with exactly $1,000, all in one-dollar bills. He gave the money to a cashier and said, "Put this money into ten bags in such a way that if I call and ask for a certain number of dollars, you can hand me over one or more bags, giving me the exact amount called for, without having to open any of the bags."

How was the cashier to do this?

Answer:

 

The contents of the bags should be $1, $2, $4, $8, $16, $32, $64, $128, $256, and $489. Notice how the contents of the first nine bags are in geometric progression.

 DAY 474

DAY 471

From a number that's odd, cut off its head,

   It then will even be;

Its tail, I pray, next take away,

   Your mother then you'll see.

 

Answer:

 

SEVEN - EVEN - EVE 

DAY 470 

Using multiplication and addition, make the digits 1-9 = 100. Each number may be used only once.

Answer:

 

9 X 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 100

DAY 469

Subtract 45 from 45, leaving 45.

Answer:

1+2+3+4+5+6+7+8+9 =45

  9+8+7+6+5+4+3+2+1 = 45   

- 1+2+3+4+5+6+7+8+9 = 45  

  8+6+4+1+9+7+5+3+2 = 45

 

DAY 468

DAY 466  MIND TICKLER
 
From Dell Penny Press Variety Puzzles
February, 2019

Find the missing number (?) and the next two numbers in the sequence:

5, 8, 13, 12, 7, 10, ?, 9 ........

Answer:

The missing number is 8. Starting from the third number, each number is equal to the sum of the digits of the previous two numbers. For example,  5+8=13,  8+1+3=12,  etc. 

The next number would be 17 (8+9), followed by 17 again (9+1+7).  

DAY 465

MATH MAGIC

Add the year of your birth + the year of birth of your child (or any younger relative). Now add to this your age (the age you will be in the current year - even if you have not reached your birthday yet). Next add the age of your child or other relative - also the age he/she will be by Dec. 31 of the current year. What do you get?

Answer:

A number exactly double the current year.

For example:
Today is Sept. 26, 2019.
I was born in 1945.
My daughter was born in 1976.
I will be 74 this year (in Oct.)
My daughter is 43 (already had her birthday).

1945 + 1976 = 3921
74 + 43 = 117
3921 + 117 = 4038  (2x2019)

DAY 464
From Reader's Digest

An old man decided that it was time to divide his herd of 18 camels among his three sons. He kept the camel he loved best for himself and had 17 left. As was the custom, he gave one half the herd to his eldest son, one third to the second, and one ninth to the youngest. How did he do it?

He added his own camel to the 17, making 18 again. 9 camels went to the eldest son, 6 to the second, and 2 to the third. 9 + 6 + 2 =17, so 1 camel was left - the one the old man loved best - and he took it back for himself.

This story illustrates an old Arabian saying: "If you give away that which you love, it will be returned to you."
***********************************************

The saying may be true, but the math isn't. What's wrong?

Answer:

1/2 + 1/3 + 1/9 = 
9/18 + 6/18 + 2/18 = 17/18 - He's one camel short.
