|Schools and Facebook: Moving Too Fast,|
or Not Fast Enough?

Problem One - A: Mission Possible
A "Shift 3" code is determined by placing an alphabet sequence above another set and shifting the bottom set three places to the right. Letters at the end of the bottom sequence are wrapped around to the front as indicated in the example below.
EG. Using the above code QBXZEBOP KBQà TEACHERS NET
Boy: While walking along the road I found a pencost !
Girl: What’s a pencost ?
Boy: Vwjpo adqz xzion
[The boy’s coded answer to the joke above is in "Shift 5"code - can you translate it?]
Problem Two: Number Cruncher
You need to fill in the blank blocks. The sum of each row, column and diagonal must equal the totals revealed in the outer layer of blocks.
For example, the first row on top must add up to a total of 147, the first column on the left must add up to a total of 171 and the diagonal starting in the top left hand corner must add up to 214.
Problem Three: Riddle me this?
Come up with creative solutions to the following Brain Crunching riddles. Read the questions carefully!
Problem Four: - Quickies
Problem Five: The last string
You have two pieces of fuse (both of which have weird shapes and they do not burn uniformly), each of which burns for exactly 1 minute. You may not use scissors, stopwatch or counting and bear in mind that the burn rate can vary along both fuses. It is essential to understand that the fuses do not BURN evenly – there are parts where they burn slowly and parts where they burn quickly. This is a three-part question:
1) How do you measure 60 secs ?
2) How do you measure 30 secs ? (HINT: Using the idea of number one)
3) How do you measure 45 secs ? (HINT: Using the idea of one and two)
