Once upon a time the King of Siam asked his worriors to measure the weight of an elephant. However the weight of the elephant was too heavy to be measured by the biggest weighting machine avaible. Help the worriors to solve the problem.

Questions 1 : The king’ s Elephant Problem

Page 3: Numerical literacy ( week 2 )

measure the weight of an elephant the weight of the elephant was too heavy to

be measured by the biggest weighting machine avaible

Help the worriors to solve the problem

Identify the problem

Page 4: Numerical literacy ( week 2 )

Cut the elephant into a part Measure the weights of all parts of elephant

x + x + x + x + x = 5x kg ( Elephant )

Draw the diagram ( chose strategy )

Page 5: Numerical literacy ( week 2 )

Using dacing ( chose stratgy )

Page 6: Numerical literacy ( week 2 )

The elephant

= volume of water displecement

Water displacement

Page 7: Numerical literacy ( week 2 )

Density = mass ( kg )volume

Let says density of water = 1 kg per liter Volume of water desplacement = 1000 liter 1 kg liter = X

1000 liter 1000 kg = x

Using Equations (checking answer)

In one of the stories in ‘One Thounsand and One Night’. Abu Nawas would only allow any traveller to fetch water from the only well in the desert after solving the following problem:

The travellers were given a 3-liter container and a 5-liter container. They have to measure exactly four and seven litres of water using the above containers. You are required to help the travellers solve the problem.

Questions 2 : Abu Nawas’ Problem

Page 9: Numerical literacy ( week 2 )

The travellers were given a 3-liter container and a 5-liter container.

They have to measure exactly four and seven litres of water using the above containers.

Help the travellers solve the problem

Identify the problem

Page 10: Numerical literacy ( week 2 )

5 liter container 3 liter container

Now, pour the water into a containers to get 4 liter and 7 liter using above containers.

Draw the diagram ( chose strategy )

Page 11: Numerical literacy ( week 2 )

1 litres + 3 litres = 4 litres

4 litres + 0 liters = 4 litres

To get 4 liters of water ( carry out the strtegy)

Page 12: Numerical literacy ( week 2 )

5 litres + 2 litres = 7 litres

4 litres + 3 litres = 7 litres

To get 7 litres of water

Page 13: Numerical literacy ( week 2 )

Using formula

Equations Lets say 3 litre – x Lets say 5 litre – y

To get 4 litre ( y – x ) + ( y – x ) =

4 2(y –x ) =

4

To get 7 litres Y + ( y – x ) = 7 Y + ( 5 - x ) = 7

To get the answers, subsititue x and y into the equations.
