Read the following text carefully and answer the questions that follow:
Peter, Kevin James, Reeta and Veena were students of Class $9^{th} B$ at Govt Sr Sec School, Sector $5,$ Gurgaon.
Once the teacher told Peter to think a number $x$ and to Kevin to think another number $y$.
so that the difference of the numbers is $10(x > y).$
Now the teacher asked James to add double of Peter's number and that three times of Kevin's number, the total was found $120.$
Reeta just entered in the class, she did not know any number.
The teacher said Reeta to form the $1^{st}$ equation with two variables $x$ and $y.$
Now Veena just entered the class so the teacher told her to form $2^{nd}$ equation with two variables $x$ and $y.$
Now teacher Told Reeta to find the values of $x$ and $y.$
Peter and kelvin were told to verify the numbers $x$ and $y.$
Image
$i.$ What are the equation formed by Reeta and Veena?
$ii.$ What was the equation formed by Veena?
$iii.$ Which number did Peter think?
OR
Which number did Kelvin think?

Read the following text carefully and answer the questions that follow:
Once upon a time in Ghaziabad was a corn cob seller. During the lockdown period in the year $2020$, his business was almost lost.
So, he started selling corn grains online through Amazon and Flipcart. Just to understand how many grains he will have from one corn cob, he started counting them.
Being a student of mathematics let's calculate it mathematically. Let's assume that one corn cob $($see Fig.$),$ shaped somewhat like a cone, has the radius of its broadest end as $2.1 \ cm$ and length as $20 \ cm.$
Image
$i.$ Find the curved surface area of the corn cub.
$ii.$ What is the volume of the corn cub?
$iii.$ If each $1 \ cm^2 $ of the surface of the cob carries an average of four grains, find how many grains you would find on the entire cob?
OR
How many such cubs can be stored in a cartoon of size $20 \ cm \times 25 \ cm \times 20 \ cm$.
