4. In a row of 10 persons A is from seventh from left end. B is from 8th from right side. Find the total how many persons are sitting between A and B in a row?
A) 3 B) 2 C) 5 D) 1
Sol: Total no of persons in a row < (Left side position of one person + right side position of another)
Note: Total no of persons in between them = [right side rank of one person + left side rank of another person] − [Total no of + 2 person]
Here, total no of persons = 10
Left + side of rank of A is = 7
Right side of rank of B = 8
15 > 10
Total no of persons between A and B
= (L + R) − (T + 2)
= (7 + 8) − (10 + 2)
= 15 − 12 = 3
(or)
5. Rajini is 38th from the left end and 12th right of Ashish who is 48th from right end then how many students are in a row?
A) 60 B) 61 C) 73 D) 64
Sol: Ashish 38th Left
by using Ashish's position Ashish = 48th right
Ashish left = 38 − 12 = 26 left side
Total = right + left − 1 = 48 + 26 − 1 = 73
by using Rajini's position Rajini = left = 38
Rajini right side = 48 − 12 = 36 Total = right side + left − 1
= 38 + 36 − 1 = 73
Ans: C

by using A's position
= Total = Left + Right − 1
= 25 + 45 − 1 = 69
Ans: C
