Rule No. 6
In a row, if the positions of two different persons are given from opposite sides of the row and a third person is sitting exactly in the middle of that two person. If total number of persons is to be calculated, then there are will be two conditions β
a) When the position of the third person is to the left side of that person whose position was given from the right side. Or when the position of the third person is to the right side of that person whose position was given from the left side.
b) When the position of the third person is to the left side of that person whose position was given from the left side. Or when the position of the third person is to the right side of that person whose position was given from the right side.
Example:
In a row there are some persons, the position of Nishant from the left side of the row is 16th and position of Shikha from the right side of the row is 11th. If Mahesh is sitting just in the middle of Nishant and Shikha and there are two persons between Mahesh and Nishant. Find the total number of persons in the row?
Solution:
A) If Mahesh is to the left of Shikha, then the number of persons in the row will be:
Shortcut Rules:
β Position of 1st person+ Position of 2nd person + twice of the number of people between the third person and any of them (which was given) + 1
β Position of Nishant + Position of Shikha + twice of the number of people between the third person and any of them (which was given) + 1
β 16 + 11 + (2 Γ 2) + 1 = 32
B) If Mahesh is to the right of Shikha, then the number of persons in the row will be:
Shortcut Rules:
β Position of 1st person+ Position of 2nd person + twice of the number of people between the third person and any of them (which was given) β 3
β Position of Nishant + Position of Shikha β twice of the number of people between the third person and any of them (which was given) β 3
β 16 + 11 β (2 Γ 2) β 3 = 20
