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.

Sum of 22

Fill in numbers such that the sum of each 3-character row is 22 while the sum of all five numbers is 30.

a
b	c	d
e

Show the answer »

The problem works out to a set of three equations:
b + c + d = 22
a + c + e = 22
a + b + c + d + e = 30Solving for c = 14, leaving d = 8 – b and e = 8 – a. In other words, c must be 14, but the other two numbers just have to add up to 8. The requirement that they be unique rules out 4 + 4, so you’re left to choose from the following combations for b + d and a + e:
0 + 8
1 + 7
2 + 6
3 + 5

The Case of Wesley and the Broken Window

How?

Monopoly has two dice, and the lowest number two dice can roll is 2. The window repair came out of Wesley’s allowance and he stopped throwing his baseball in the house.
