IF YOU DIVIDE 30 BY HALF RIDDLES WITH ANSWERS TO SOLVE - PUZZLES & BRAIN TEASERS

The $9 paid by each guest accounts for the $2 that went to the bellhop. So rather than adding $27 to the $2 kept by the bellhop, the $27 accounts for the bellhops money. The $27 plus the $3 kept by the guests does add up to $30. Did you answer this riddle correctly?
YES  NO  

Current Future Past

Princess x 2z (x+y)/2
Prince y x z

I then created three equations, since the difference in their age will always be the same.

d = the difference in ages

x y = d
2z x = d
x/2 + y/2 z = d

I then created a matrix and solved it using row reduction.

x y z

1 -1 0 d
-1 0 2 d
.5 .5 -1 d

It reduced to:

x y z

1 0 0 4d
0 1 0 3d
0 0 1 5d/2

This means that you can pick any difference you want (an even one presumably because you want integer ages).

Princess age: 4d
Prince age: 3d

Place 1 white marble in one bowl, and place the rest of the marbles in the other bowl (49 whites, and 50 blacks).

This way you begin with a 50/50 chance of choosing the bowl with just one white marble, therefore life! BUT even if you choose the other bowl, you still have ALMOST a 50/50 chance at picking one of the 49 white marbles. Did you answer this riddle correctly?
YES  NO

The book costs $2.

Let the cost be X. We know that:
X = 1 + X/2

Solving for X will give 2. Did you answer this riddle correctly?
YES  NO  

We can easily solve this mathematical problem by using the following mathematical process.

Initial loss amount = Rs. 1000

Now, we have to calculate the recovered amount,

As the man spends Rs. 700 in the shop, the shop owner will surely provide the man goods/services of Rs. 700. So, nothing will be recovered in this case.

Now, the man gave Rs. 1000 against the goods/services of Rs. 700 and got Rs. 300 change, so there will be no recovering of money for the shopkeeper.

Final loss = Initial loss - Recovered amount = 1000-0 = Rs. 1000 Did you answer this riddle correctly?
YES  NO  

4 daughters (sisters) and 3 sons (brothers)

A girl has as many brothers as sisters : If one of the daughters count her siblings, she would count - 3 sisters (3 remaining daughters in the family) and her 3 brothers (3 Sons in the family). So, it makes the statement true that the girl has as many brothers as sisters.

Each brother has only half as many brothers as sisters. This means, when one of the sons count his siblings, it would be 2 brothers (remaining 2 sons of the family) and 4 sisters (All 4 daughters in the family). 2 is the half of 4. It agrees to the condition that

each brother has only half as many brothers as sisters.

Therefore the answer is :

The family has 4 daughters (sisters) and 3 sons (brothers). Did you answer this riddle correctly?
YES  NO
