IF YOU DIVIDE 30 BY HALF AND ADD TEN WHAT DO YOU GET 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

Someone bowled a strike. The ten white men are the pins, the dirt road is the bowling alley (its not dirt, but its the color of dirt, and if it said a smooth wooden alley it wouldnt be much of a riddle). Three eyes as black as night are the finger holes in the bowling ball. Did you answer this riddle correctly?

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

Just to reiterate the hint, if you knock down a single pin, for example at the far left of the back row, then repeat the same identical shot on your second throw, you'll score 0 points for your second throw (because there's no pin there anymore), but it's not a gutter ball as the shot did not enter the gutter.

YES  NO
