This BrainBashers safe has a rather unusual control panel.
In order to open the safe, you have to press every single square once only, in the correct sequence, ending on the square marked E.
Each square indicates which square to press next, for example, 2U means move up 2 squares and 3R means move right 3 squares.
Can you determine which square you must start with?
| 3R | 4R | 2R | 2D | 2R | 4D | 2D |
| 2R | 1U | 1U | 3D | 2D | 1R | 2L |
| 3D | 1D | 3R | 1R | 2L | 4L | 1D |
| 1U | 4R | 2L | 3D | 2D | 2L | 4L |
| 4U | 1L | 2D | E | 2R | 1D | 4L |
| 1R | 1D | 1R | 4U | 2R | 3L | 1D |
| 5U | 5U | 2L | 2R | 2U | 5U | 2L |
Note: this puzzle is not interactive, and the safe buttons cannot be clicked.
Puzzle 238
I recently went to the shop and purchased 4 items.
Three of the items cost:
$1.50
$3.00
$4.00
There was quite a long queue, and as I was quite bored, I was playing with my pocket calculator while I waited.
Very curiously, the 4 prices added to the same number as I got when I multiplied the 4 prices together.
What was the price of the 4th item?

Many years ago, a cruise liner sank in the middle of the Atlantic Ocean. The castaways luckily landed on a remote desert island.
There was enough food for the 135 people to last four weeks.
Nine days later a rescue ship appeared, unluckily this ship also sank, leaving an additional 36 people stranded on the island to now share the original rationed food.
The food obviously had to be re-rationed, everyone was now on three-quarters of the original ration, so how many days in total would the food last, from the day of the original sinking?
