Math Puzzle 1
Old Granny Adams left half her
money to her granddaughter and half
that amount to her grandson. She left
a sixth to her brother, and the
remainder, $1,000, to the dogs’ home.
How much did she leave altogether?
Answer
This one might have tripped you up! But the trick is not to focus
on the hypothetical amounts, but on the fractions: Adding one
half, one quarter, and one sixth tells us that the total is a fraction
of twelfths (2+4+6=12). You can also think about it as 6/12, 3/12,
2/12, which equals 11/12. If the remainder is $1,000, that must be
one-twelfth, so the total is $12,000.

Math Puzzle 2 …. Math Fallacy
‘Your Income is the same as that of a Millionaire!’
Proof Suppose the income of or a millionaire is $ x and your income is $ y.
Let us say $ S is the sum of the two incomes.
Hence x + y = S (1)
Multiply both sides of the Equation (1) by the factor (x – y)
(x – y)(x + y) = (x – y )S
So x2 – y2 = xS – yS (2)
Rearranging Equation (2),
x2 – xS = y2 - yS (3)
Completing the square for both sides of the Equation above,
x2 – xS + ( - S/2 )2 = y2 – yS + ( - S/2 )2
we get ( x – S/2 )2 = ( y – S/2)2 (4)
Taking the square root of both sides, hence
x – S/2 = y – S/2 Therefore x - y !
So the income of a millionaire is the same as yours!

The valid root
is the
negative one.
Then you will
