Great! Just as expected, the shopkeeper won! He gave Jack, the magnets he required and also the disc. Math sure is a life saver! Getting superconductor wires was a big problem. Since it was discovered in future, nobody knew about it. So, Jack decided to build the wire himself. From his data sheet, he found out the different lengths (in cm) of the superconducting wires required as:

24 6 34 9 56 7 18 29 50 43 37

What is the range of the length of the superconducting wires Jack requires?

50 cm

Solution

The correct option is A
50 cm

24 6 34 9 56 7 18 29 50 43 37

Range = Highest observation - Lowest observation

Highest observation = 56

Lowest observation = 6

So, range = 56 - 6 = 50

The range of length of superconducting wires required is 50 cm.

After all these questions, William mentioned that the chart looks like a chart of several bars. Jack could relate to it as he knew that William was going to invent them in future!

To return to the future, he needed to charge the super batteries. Though nobody knew how to generate electricity there, Jack, with the help of magnets and superconductor wires, successfully built a micro hydro generator.

He went to the church and started charging the super batteries every day. Meanwhile, Jack played the game of Ludo with William to pass time. This game is played by throwing a 6 faced die with numbers from 1 to 6 on its 6 faces. To win, Jack had to get a 4. What is the probability that he will win the game?

Set for future, landed in past! When Jack tried to look for the problem, he found something that made his day even worse. He didn’t bring the toolbox with him. Overconfidence can really be so bad! But he was sure that he will never find them in a forest. So, he decided to go looking for nearest city. Jack checked his encyclopedia for the places around. He found the following data:

$\begin{matrix} Name of the place & Distance (in kms) & Population Cottage & 9.5 & 4, 000 Arsenal & 9.5 & 1, 000 Britannia & 35.3 & 5, 000 \end{matrix}$

Jack analyzed the table carefully, hid his time machine under some tall bushes and started to go towards __.

On the way, Jack was thinking that he can’t go to $2015$ because it is future to him now. If he tries to go to future, he will end up in past again. But what went wrong?

Though Jack is a great mathematician, he can’t remember about each and every part of the machine. So, he took out the data sheet to know which part was the most important. There was a chart which gave the priority of different devices. Which device is the most important?

$\begin{matrix} Device & More numbers stars = High priority Time Direction Module & ★ ★ ★ ★ ★ Batteries & ★ ★ ★ AYC(Analog Year counter) & ★ Toolbox & ★ ★ \end{matrix}$

The storekeeper was very happy to get a solution to his problem. When Jack told this story to Jacob, he was so curious to know how Jack solved the problem of the storekeeper. Then Jack explained the concept of mode to Jacob.
