The Age of Three Daughters

I was visiting a friend one evening and remembered that he had three daughters. I asked him how old they were. “The product of their ages is 72,” he answered. Quizzically, I asked, “Is there anything else you can tell me?” “Yes,” he replied, “the sum of their ages is equal to the number of my house.” I stepped outside to see what the house number was. Upon returning inside, I said to my host, “I’m sorry, but I still can’t figure out their ages.” He responded apologetically, “I’m sorry, I forgot to mention that my oldest daughter likes strawberry shortcake.” With this information, I was able to determine all three of their ages. How old is each daughter?

3, 3, and 8. The only groups of 3 factors of 72 to have non-unique sums are “2 6 6” and “3 3 8” (with a sum of 14). The rest have unique sums:

2 + 2 + 18 = 22
2 + 3 + 12 = 18
2 + 4 + 9 = 15
3 + 4 + 6 = 13

The house number alone would have identified any of these groups. Since more information was required, we know the sum left the answer unknown. The presence of a single oldest child eliminates “2 6 6”, leaving “3 3 8” as the only possible answer.

Hidden Gems

Find the names of 10 gems or precious stones hidden in the following story. Each one spans at least two words.

Sir Gade rode toward a castle atop a zebra at a steady gallop, a long way from home. He arrived at the gate and the keeper knelt in shame. “Thy steed must be tired.” Sir Gade replied, “I am on direct orders from the King. Let me through.” A cougar, nettled by the noise, emerged from a shrub. “You must save me!” cried the gate man. Sir Gade, eyes filled with rancor, alighted and gazed toward the sky. An item fell from his cloak as drove his sword into the cougar’s spine. “Let me pass!” cried Sir Gade. The gate keeper, stunned from his saga, tentatively opened the gate, then retrieved the fallen item.

1. topaz – “atop a zebra”
2. opal – “gallop, a long”
3. amethyst – “shame. Thy steed”
4. diamond – “replied, I am on direct”
5. garnet – “cougar, nettled”
6. ruby – “shrub. You”
7. coral – “rancor, alighted”
8. kyanite – “sky. An item”

Word With All 26 Letters

What word contains all 26 letters?

Alphabet (unfortunately there aren’t any actual dictionary words with every letter in the alphabet, so this gimmicky, somewhat unsatisfying answer has to suffice).

I’m A Sifter

I’m a sifter of a memorable shape,
You can eat a variety of me, but I can be toxic,
I can cause severe pain if you’re not careful,
And the action I describe could hurt as well.

What am I?

A kidney.

Kidneys filter your blood and are shaped like kidney beans, which you can eat. Red kidney beans contains high amounts of phytohemagglutinin (quite the word, eh?) and can be toxic if not soaked and boiled. Kidney stones can be extremely painful and if a kid knees you in the stones, that would also be unpleasant.
