1. The Oklahoma Kite Company
The Oklahoma Kite Company makes kites, using best
quality rip-stop nylon to cover the framework
which is constructed of lightweight glass-fibre rods.
In order to minimize costs the company must use
all the materials with as little waste as possible.
One of the problems they have in
the company is how to fit the kite
shape onto a long rectangular sheet
of nylon in the most economical way.
The dimensions of a kite are shown
in the diagram and the nylon
for making the kites is available in
rectangular strips which can be up to
4 metres wide and up to 120 metres long. 
30cm
120cm
60cm

2. For each configuration shown, calculate the minimum width of nylon necessary, the length required to produce 12 shapes and the percentage waste of material in each case A   B  C

3.  D  E

4. In each of the arrangements calculate the % waste in producing
48 kites per strip of nylon
120 kites per strip of nylon
180 kites per strip of nylon
Which is the most economical method?
If it is decided to use the maximum available length
of 120 metres, what are the % waste figures now?
Try configurations other than those shown above
and see if you can find the most efficient way in which kites
can be cut from the rectangular sheets.

5. 1. The two jugs when full can hold 18 litres and 30 litres.
Exercise:- A girl has an unlimited supply of water from the tap in her house. She also has two jugs and a large water tank which has a tap on it as shown.
1. The two jugs when full can hold 18 litres and 30 litres.
Explain how she can measure out an exact amount of
(i) 24 litres (ii) 6 litres
using the jugs and the water tank.
2. Suppose the two jugs hold 25 litres and 14 litres.
Explain how she can measure out
(i) 8 litres (ii) 13 litres

6. A solution:
Identify the containers as A (small) and B (large) One way of doing it is to - Fill A and pour that into B. Fill A and pour as much as possible into B. This will leave 1 litre in A Empty B Pour the 1 litre from A into B Fill A and pour that into B. There will then be 4 litres in B.
