Question of the Week Monday 19 September


Each question is worth one point.

1.     Why is it better for manhole covers to be round rather than square?

2.     Mohendra the dog can't remember where he buried his bone-under the rock, in the garden, under the porch, or under the tree. If only one of the following sentences is true, where is Mohendra's bone? 
The bone is under the rock.
The bone is in the garden or under the tree.
The bone is under the rock or under the porch.
The bone is not in the garden.
3.     Three men jumped on the same diving board and the same pool. Two of the three got their hair wet and the third one doesn't. Why?

4.      I become bigger when they take something away from me. I become smaller when they add something on me. What am I?

5.     What is wrong with this statement: “Batteries run out of charge.”?

Diviértase!!

  1. 1)A square manhole cover can be turned and dropped down the diagonal of the manhole. A round manhole cannot be dropped down the manhole. So for safety and practicality, all manhole covers should be round!

  2. 3) Because he was bald. So he couldn't have wet his hair because he didn't have any hair. Or... he could've just been wearing a swimming cap
