Numerical LiteracyProblem solving
Solution Prepared by : Mohamad Nasrun B Mohamad Zaki Mohd Aidil B Othman Mohd Azri B Mat Idris
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
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
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 )
Using dacing ( chose stratgy )
The elephant
= volume of water displecement
Water displacement
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
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
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 )
1 litres + 3 litres = 4 litres
4 litres + 0 liters = 4 litres
To get 4 liters of water ( carry out the strtegy)
5 litres + 2 litres = 7 litres
4 litres + 3 litres = 7 litres
To get 7 litres of water
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.
See carefully and try to understand ^_^
Act the situation ( checking answer )
