उत्तर
For getting the same work a (× 102) machine does, we have to (× 22) and (× 52) machines hooked together.
∴ × 102 = × 100
Similarly, × 22 × 52 = × 4 × 25 = × 100

Suppose you have a stretching machine which could stretch almost anything. For example, if you put a 5 metre stick into a (× 4) stretching machine (as shown below), you get a 20 metre stick. Now if you put 10 cm carrot into a (× 4) machine, how long will it be when it comes out?
Two machines can be hooked together. When something is sent through this hook up, the output from the first machine becomes the input for the second. Which stretching machine does the same work as two (× 2) machines hooked together?
