Ranjan ranks 18^{th} in a class of 49 students. What is his rank from last?
Here, 49 – 18 = 31
So, Ranjan’s rank = 31 + 1 = 32^{nd} form the last.
If Aman finds that he is 12^{th} from the right in a line of boys and 4th from the left. How many boys should be added to the line such that there are 35 students in the line?
No. of boys in the line = 12 + 4 – 1 = 15.
No. of boys to be added = 35 – 15 = 20
In a queue, Ravi is 13^{th} from the back Amar is 12th from the front. Hari is standing between the two. What should be the minimum number of boys standing in queue?
1 2 3 4 5 6 7 8 9 10 11 12 13
Minimum no. of boys = 13 + 1 = 14
In a row of boys Raja is 10^{th} from the left and Pramod, who is 9th from the right interchange their positions, Raja becomes 15th from the left. How many boys are there in the row?
Raja’s new position is 15th from the left and this is the same as 9th position from the right for Pramod.
No. of boys = 15 + 9 – 1 = 23
Shankar ranked 7^{th} from the top and 34th from the bottom in a class. How many students are there in a class?
Total number of students = 6 + 1 + 33 = 40
Naresh ranks 5^{th} in a class, Vikas is 8th from the last. If Raju is 6th after Naresh and Just in the middle of Naresh and Vikas. How many students are there in the class?
Total no. of students = 5 + 6 + 6 + 8 – 1 = 24
If in a single line, Mohan is 23^{rd} from both the ends. How many boys are there in the class?
Required no. of boys = 22 + 1 + 22 = 45
Saket is 7 ranks ahead of Manoj in a class of 50. If Manoj’s rank is 17^{th} from the last, what is Saket’s rank from the start?
Manoj’s rank is 17th from the last.
Saket’s rank = 17 + 7 = 24th from the last.
No. of students ahead of Saket = 50 – 24 = 26
