SHOES MAN WHISTLE WITH TO RIDDLES WITH ANSWERS TO SOLVE - PUZZLES & BRAIN TEASERS

The third equation has a term with a pair of whistles. The last line involves a single whistle.

Furthermore, the man in the second and third lines are wearing a whistle, but the man in the last line is not wearing a whistle. Presumably the value of the whistle should be accounted for to get the correct answer.

The pictures can be translated into the following equations:

shoes + shoes + shoes = 30
shoes + (man + whistle) + (man + whistle) = 20
(man + whistle) + 2(whistles) + 2(whistles) = 13
shoes + (man) x (whistle) = ?

From the first equation we can solve for the shoes value:

shoes + shoes + shoes = 30
3(shoes) = 30
shoes = 10

We can then solve the second equation for the (man + whistle) value:

shoes + (man + whistle) + (man + whistle) = 20
10 + 2(man + whistle) = 20
2(man + whistle) = 10
man + whistle = 5

Then we solve the third equation for the whistle:

(man + whistle) + 2(whistles) + 2(whistles) = 13
5 + 4(whistles) = 13
4(whistles) = 8
whistle = 2

We also need to solve for the value of the man:

man + whistle = 5
man + 2 = 5
man = 3

Now we can evaluate the final expression, remembering the order of operations that multiplication should be evaluated before addition:

shoes + (man) x (whistle) = ?

10 + 3 x 2
= 10 + 3 x 2
= 10 + 6

1) The girl was wearing a dress at the graveyard. It was dark, so she hadn't noticed where she stuck the knife in the ground. She accidently stuck it in her dress (and the girl DID NOT get hurt by the knife in any way). That is what prevented her from running away.

2) Since the knife had her stuck, she was frighted that the rumor of the bony hand was true and had grabbed her, trying to pull her into the ground. She was truly terrified and died of fright. Did you answer this riddle correctly?

Only one is going to St. Ives...the narrator! All of the others are coming from St. Ives. The trick is that the listener assumes that all of the others must be totaled up, forgetting that only the narrator is said to be going to St. Ives. If everyone mentioned in the riddle were bound for St. Ives, then the number would be 2,802: the narrator, the man and his seven wives, forty-nine sacks, three hundred forty-three cats, and twenty-four hundred and one kits.
