Hexagonal Base Pyramid and Magic Squares answers needed pls

Postby optimistforum » Fri Apr 06, 2012 6:31 am

Hi

I am stuck on two questions. Can you help please?

1. For this magic square question, the numbers are written in old imperial English currency. Can someone supply the answers from the link below; I am perplexed by it:

2. This question has a hexagonal base pyramid, in Fig 1. Can someone please explain the answer to (d). I have it is as 16, but the answers have it as 18.

I cannot rise to this challenge of these two questions.

Surely, there must be great mathematicans that can proffer their thoughts on these two questions. Please!!!!

PS, these have been taken from a General Ability book, called Spotlight in Reasoning. This booked morphed into Test Your Intelligence - which I have mentioned on the GEP page.

Hi,

Well I cannot call myself a Mathis genius, just pondered over the questions just now.

1) is the answer in each square derived after multiplying the previous square with 2? If yes then answer would be 128d..
Not sure.. :?

What is the answer given?

2)For this question, we have to make figure 1 stand on table first right? Then looking.. There are 6 faces ( sides) on the shape.. Each is triangle.. 1 triangle has 3 angles. So 6 x 3 = 18.. Does this sound logical??

He he sorry may be this explanation is correct :shrug:

Do update on this ...sounds interesting...

Hi Mother 77

The administrator at the British Library read the answers from the answer book over the phone. But my answers below to the questions are in black font, and library answers in red font. I an still awaiting her to email me some scanned answers. Until then

For the Magic squares question, going from left to right, I had:

1/2d, 1d, 2d
4d, 8d, 16d
32d, 64d, 128d

I am still awaiting library answers



Hexagonal pyramid question

a) 6 (6)

b) 5, (5)

c) 7, (7)

d) 15, (18)

Maybe, I have been pedantic, but as it said "how many angles you can see", then I can physically see only 3 triangles and the base (other 3 trangles are hidden - unless you walk around the table):

3 triangles = 3 times 3 = 9

6 angles in the hexagon base = 6

9 + 6 = 15

For question 2, part d.. Your answer should be based on 6 sides which you can see when the figure 1 Is placed on table standing on its base.. That's how the question begins right?

Hi Mother 777

I can see you are right, and so 18 is the answer. :smile:

In relation to the magic squares, the answers will be emailed to me, and I will disseminate these to you asap.

Many thanks.

Hi Mother777

Your original answers and mine were both right.

The British Library scannned and emailed me the answers. Here is the answer to teh Magic Squares questions (with some rationale, too)

The confusion has arisen because they are using old English currency, pre-decimalisation (ie pre 1971). I started infant school whgen this came into being and therefore I have little context about it.

1d = 1 penny

2 half pennies = 1d

12 pennies = 1 shilling or /


20 shillings = 240 pennies = £1


The answer is:

Double each amount:- 1/2d (ignore the / sign, this is a half penny), 1d, 2d, 4d, 8d, 1/4d, 2/8d, 5/4d, 10/8d. The context below shows how each number is derived using shillings (/) and pence (d):


Double each amount:- 1/2d (ignore the / sign, this is a half penny), 1d, 2d, 4d, 8d, 1/4d ( this is 16d = 1 shilling and 4 d), 2/8d (this is 32 d = 2 shillings and 8d), 5/4d (this is 64d = 5 shillings and 4d), 10/8d (this is 128d = 10 shillings and 8d)

Wow didn't know that counting pennies and shillings could be so complicated :)
Am glad the solution is clearly explained.. Should really appreciate the British Library for taking the effort to scan and send to you.

Was just wondering, from where you are getting these questions? What is your purpose in solving these?

Hi Mother777

I gave some guidance to the GEP section on GAT books. Look at this link, as the following questions copmes from the book: Test Your intelliegence:

http://www.kiasuparents.com/kiasu/forum ... 6&start=30

They are published here in England; they are old but still useful.

How many right angles in this square

Postby optimistforum » Sun Apr 15, 2012 5:31 am

Hi

Can someone please look at question 11 in the attached link. It asks how many right angles in a big square shape that comprises 4 smaller squares.

The answer is 16.

I agree that a square has 4 right angles, therefore 4 squares will have 16 right angles.

But will there be any extra ones for the bigger square; so should it become 16 + 4 = 20
