“Apparently children can solve this in less than 20 seconds” Which children? A few? Some? All? Has every child in the world been presented with this problem and have, in the main, solved it within 20 seconds? Or have just two? Clearly the opening sentence is the real test of aptitude for adults engaging with this 'problem'.
I had a similar(ish) problem. Just prior to pulling away the cars driver tipped a load of McDonalds cartons, paper cups and wrappers on the floor thus rendering it impossible to see the number. He then flicked the rods at me, called me an old **** just prior to turning on a cacophony of drum and bass at full tilt and wheel spinning off. His passenger was leaning out of the window shouting " Braap braap". I just got confused and had to go for a lie down. I'll go back later when it's a bit more serene to try and work it out. Good heavens.
Gastons out for at least a month! He played his best game by far for us v Chelsea,now he's injured ffs. The answers 2 by the way.
Call me Mr Thicko but I've just spent 3 hours trying to crack this and I can't. Then I realised, it's a trick question. There isn't a number under the car. It's parked on a yellow marked restricted parking spot for diabled drivers without displaying the relevant badge. This is the sort of person who gets us all a bad name. What a xxxx! Only solved it with the clue.
For those who haven't got it yet, here is the solution; starting from the left add 10 to the original number (16) then subtract the square root of 16 before deducting the nearest whole number to pi and taking away the cube root of 9; square this and double it and deduct 2 squared. double 10 then twice moves us on to where we add just the individual singleton; a further dozen gets us there - or is a negative 1? Simples!
Nice ref to Oz being upside down. You bet your sweet bippy I did. These are old 'bonus' questions from years ago The favourite was "How much is sevenpence ha'penny times 32,000" which most just skipped over but it can be worked out in 10 seconds - without a calculator.
It's bleeding obvious that. The answer's '****ing loads'. The answer's not quite as simple as it appears if, as convention dictates, it's in £sd. Assuming the language means it's pre-decimal. Although the numbers make it easier provided you know how the old currency worked.
