Question 147
Stretching Machine
Suppose you have a stretching machine which could stretch almost anything. e.g. If you put a 5 m stick into a (x 4) stretching machine (as shown below), you get a 20 m stick.
Now, if you put 10 cm carrot into a (x 4) machine, how long will it be when it comes out ?
According to the question, if we put a 5m stick into a (x 4) stretching machine, then machine produces 20 m stick.
Similarly, if we put 10 cm carrot into a (x 4) stretching machine, then machine produce 10×4=40 cm stick.
