Concepts Regarding the Order and Ranking Topic
Case 1
Finding the total number of people when the ranks of one person are given
Total number of people = R1 + R2 – 1
Here R1 and R2 represent the rank of a person from both sides.
Ex: In a row, the position of Aman is 28th from the left side while the position from the right-hand side of the row is 33rd. How many total numbers of people are there in the row?
Total number of people = (Position of Aman from left side + position of Aman from the right side) – 1
= (28 + 33) – 1 = 59
Also, to find the position of a person from the opposite side when the rank of one side along with a total number of people is given.
= (Total number of people – position of the same from a given side) + 1
Case 2
When in a row, the position of two people is given and their positions are interchanged. Also, after interchanging the position of the 1st person, it is given from the similar side as before the interchanging.
So, the new position of the 2nd person from a similar side before interchanging the = position of the 2nd person from the similar side before interchanging + (position of a 1st person after interchanging – position of the 1st person before interchanging from a similar side)
Total number of people = sum of positions of the people from both the sides – 1
Number of people between two people = Difference in the position of a person whose position is from a similar side after and before interchanging is given – 1
Ex. In a row of boys, Pramod us 14th from left and Kanu is 20th from the right. If both of them interchange the position than Pramod becomes 17th from left. Thus, what will be Kanu’s position from the right?
Total no. of girls = right end + left end – 1
= 17 + 20 – 1 = 36
Kanu’s position from right side = total girls – left end + 1
= 40 – 15 + 1 = 26
