Calendar - Finding day on Next year same date

Example 1
If 1st October 2023 is Sunday, what will be day on 1st October 2024?
Solution
When we are finding day for same date on next year then just check if the range which we are finding (1st October 2023 to 1st October 2024 in our case)
1) If it is having 29th February in range then 2 day gets added.
2) If it is not having 29th February in range then only 1 day gets added.

Here as we can see 2024 is leap year and we will get 29 February 2024 in range (1st October 2023 to 1st October 2024).So, 2 days will be added.
Sunday + 2 = Tuesday
1st October 2024 will be Tuesday

Ranking Test - Finding number of people in row

Example 1
All students are standing in single row. Anuj is 19th from both ends. How many students are there in row?
Solution
Anuj is 19th from both ends. So there will be 18 people to left of Anuj and 18 people on right of Anuj.
18 + 18 + 1(Anuj) = 37
There are 37 students in row

Shortcut method
Assume position in nth from both side.
Total number of people in row = 2n - 1
Here n = 19
2n - 1 = (2 X 19) - 1 = 37
There are 37 people in row

Example 2
All students are standing in single row. Mayuri is 31st from both ends. How many people are there in row?
Solution
As Mayuri is 31st from both ends
Number of people = 2n - 1 = (2 X 31) - 1= 61
There are 61 people in row

Ranking Test - Finding position from other Side

Example 1
There are 30 students in Row. If Nikita is 8th from left side then what is Nikita's place from right side?
Solution
When we say Nikita is at 8th place from left it means there are 7 students to left side of Nikita.
Also there are total 30 students so after Nikita there are (30 - 8 = 22 Students)
So Nikita's place from Right will be 22+1 = 23rd

Shortcut Method
Assume number of students as Given number + 1
Subtract left side position from it
31 - 8 = 23 rd position from right.

Nikita is at 23rd place from right side

Example 2
There are 50 students in Row. If Sunil is 18th from right side then what is Sunil's place from left side?
Solution
Assume number of students = 50 + 1 = 51
Place from right = 18
Place from left = 51 - 18 = 33rd
Sunil is at 33rd place from left side

Categorize following sets as Finite Set or Infinite Set

1) C = {0}
1 element so Finite Set.

2) D = {x : x is natural number}
We have infinite natural numbers so Infinite Set

3) E = { x : x is prime nunber and x > 1}
We have infinite prime numbers So Infinite Set.

4) F = {x : x is perfect square}
We have infinite natural numbers and their squares will be perfecr square only.
So Infinite Set.

Types of Sets Based on number of elements in set

Finite Set
If we can count number of elements in Set exactly it is called as Finite Set.
Please note even though there is no element in Set is Finite Set.

Examples:
A = {1, 2, 4, 6}
Here we have 4 elements which we can count.

B = { }
0 elements here

D = { x : x is prime number between 1 and 100}
There are 25 prime numbers. So that we can count.

Infinite Set
If we can not count number of elements in Set or it has infinite number of elements it is called as Infinite Set.

Examples:
I = Set of Integers

E = {2, 4, 6, 8, 10.........}

O = {1, 3, 5, 7......}

Types of Sets Based on number of elements in set

Empty Set
If there is no element ( 0 element) in Set, it is called as Empty Set.
Please note if there is element as {0} it is not empty set as 0 is counted as element
It is usually denoted by ∅

Examples:
∅ ={ }
Set of Natural numbers less than 1

*Singleton Set*
If there is only 1 element in Set, it is called as Singleton Set.

Examples:
A = {5}
B = {a}
C = Set of Even prime numbers

Try it yourself

Categorize following sets as Empty Set or Singleton Set

1) C = {0}
2) D = {x : x is vowel in word Maths}
3) E = { x : x is prime nunber and x < 3}
4) F = {x : x is even number, 10 > x > 12}

Numbers - Try it yourself
What least number should be subtracted from 3000 so that answer will be completely divisible by 30, 36, 48

Solution

30 = 2 X 3 X 5
36 = 2 X 2X 3 X 3
48 = 2 X 2 X 2 X 2X 3
LCM:
2 X 2 X 2 X 2 X 3 X 3 X 5 = 720

So every multiple of 720 will be divisible by 30, 36, 48

Check multiple of 720 which is less than 3000.
On dividing 3000 by 720 we get quotient 4

720 X 4 = 2880
2880 is nearest to it (3000 - 2880 = 120)
We need to subtract 120 from 3000

Union
When we take all unique elements both sets, it is called as Union of Sets.
A = {1, 2, 3, 4, 5}
B = {2, 3, 5, 7, 8}

Union is shown by symbol U
(A U B) = Take unique elements from A, Take unique elements from B, Whichever repeating in both sets take them 1 time only.

A has {1, 2, 3, 4, 5}
B has { 2, 3, 5, 7, 8}
(A U B) = {1, 2, 3, 4, 5, 7, 8} (2, 3, 5 coming in both sets we will write them 1 time only)

Intersection
When we take only common elements from both sets, it is called as Intersection of Sets.
Intersection is shown by symbol ∩

A = {1, 2, 3, 4, 5}
B = {2, 3, 5, 7, 8}
(A ∩ B) = Take elements which are available in both sets
Here 2, 3, 5 are available in both A and B.
(A ∩ B) = {2, 3, 5}

If we count distinct elements from Set it is called as cardinal number of Set.

Example:
A = {1, 2, 3, 4, 5}
Here we can see total 5 unique elements 1, 2, 3, 4, 5
So cardinal number of set A is 5.

Sets Rule Based or Set builder form
Writing all elements in set is not always practical.

Let us assume we need to write down all students studying in ABC school. If we start writing name of all students it is really very much time taking and sometime practically not possible.

So, we write it in more systematic way.

Colon(:) you can read it as Set of All such that.
B = {x : x is student studying in ABC school}
We will read this as:
Set B is set of all x, such that x is student studying in School ABC

Write down following using Set builder method.

1) {1, 2, 3, 4, 5}
A = {x : x is natural number less than 6}
Or
A = {x : x is natural number, x > 0 and x < 6}
Or
A = {x : x is natural number, 0 < x < 6}

2) {a, e, i, o, u}
V = {x : x is vowel in English alphabet}

3) {Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday}
