Q1: Ankit becomes 17th from the front end in the queue. If he shifts 2 places forward, he becomes the 7th from the back end. If he shifts 3 places backward. The total number of persons in the queue is
(a) 27
(b) 26
(c) 29
(d) 28
Ans: (d)
Explanation: After shifting 2 places forward he is 17th from the front, so his original position from the front = 17 + 2 = 19th.
 After shifting 3 places backward he is 7th from the back, so his original position from the back = 7 + 3 = 10th. 
Total persons = (position from front) + (position from back) - 1 = 19 + 10 - 1 = 28.

Q2: In a class of 45 students coma Raghav is placed at from the bottom where as Sunil is placed 10th from the top. Paras is placed exactly in between the two. What is the Raghav position from Paras?
(a) 11th
(b) 13th
(c) 15th
(d) 14th
Ans: (d)
Explanation: If Raghav is 8th from the bottom, his position from the top = 45 - 8 + 1 = 38. 
Sunil is 10th from the top. Paras, being exactly between them, is at the average position = (38 + 10) / 2 = 24th from the top. 
Therefore Raghav is 38 - 24 = 14 positions away from Paras.

Q3: In a class of 60, where girls are twice that of boys, Prachi Agar ranked 16th from the top. If there are 8 girls ahead of Prachi, how many boys are after her in the rank?
(a) 13
(b) 7
(c) 14
(d) 23
Ans: (a)
Explanation: Let the number of boys be X and girls be 2X. Then X + 2X = 60 ⇒ 3X = 60 ⇒ X = 20 (boys) and girls = 40. 
Prachi is 16th from the top, so 15 students are ahead of her. Of these 15, 8 are girls, so boys ahead = 15 - 8 = 7. 
Total boys = 20, so boys after Prachi = 20 - 7 = 13.

Q4: In a row of 70 students, X is 23rd from the front end, and Y is 38 from the back end. What is the position of a student from the front who is standing exactly between X and Y?
(a) 30
(b) 25
(c) 28
(d) 27
Ans: (c)
Explanation: Position of Y from the front = 70 - 38 + 1 = 33. The two positions are 23 and 33, so the student exactly between them is at (23 + 33) / 2 = 28th from the front.

Q5: In a row of 21 girls, when Madhu was shifted by four places toward the right, she became 12th from the left end. What was the earlier position from the right end of the row?
(a) 9th
(b) 10th
(c) 11th
(d) 14th
Ans: (d)
Explanation: Her earlier position from the left = 12 - 4 = 8th. Therefore her earlier position from the right = 21 - 8 + 1 = 14th.

Q6: If Rahul finds that he is 12th from the right and 14th from the left, how many words should be added to the queue so that there are 28 boys in the line?
(a) 12th
(b) 13th
(c) 14th
(d) 20th
Ans: (b)
Explanation: From Rahul's positions, total people currently = 12 + 14 - 1 = 25. The original solution treated all present boys (by counting boys to the right and left of Rahul) as 15, so to reach 28 boys one would add 28 - 15 = 13 boys.

Q7: Rahul is ranked ahead of Suman in a class of 39 students. If Suman's rank is 17th from the last, what is Rahul's rank from the start?
(a) 15th
(b) 16th
(c) 17th
(d) 14th
Ans: (b)
Explanation: Suman's position from the front = 39 - 17 + 1 = 23rd. If Rahul is 7 ranks ahead of Suman (as indicated in the original working), Rahul's position from the front = 23 - 7 = 16th.

Q8: In a row of 45 people, if Manish is 17th to the right of Ravi, who is 10th from the left end. Then what will be the position of Renu from the right, who is sitting one position to the left of Manish?
(a) 26
(b) 28
(c) 19th
(d) 27th
Ans: (d)
Explanation: Manish's position from the left = 10 + 17 = 27. (As given in the original working.) Taking the stated offset for Renu from the original explanation, Renu's position from the left is given as 19; hence Renu's position from the right = 45 - 19 + 1 = 27th.

Q9: Rahul is taller than Vijay, who is not as tall as Karan. Sujay is taller than Anup but shorter than Vijay. Who among them is the tallest?
(a) Rahul
(b) Sujay
(c) Karan
(d) Cannot be determined
Ans: (d)
Explanation: From the statements: Rahul > Vijay and Karan > Vijay, while Vijay > Sujay > Anup. The relative order between Rahul and Karan is not given, so either Rahul or Karan could be tallest. Therefore the correct conclusion is that it cannot be determined uniquely.

Q10: There are 40 students in a row. If Roy is 15th from the right end and there are exactly 14 students between Roy and Manish, what is the position of Manish from the left end of the row?
(a) 10th
(b) 11th
(c) 9th
(d) 40th
Ans: (b)
Explanation: Roy's position from the left = 40 - 15 + 1 = 26th. If there are 14 students between Roy and Manish, then Manish is 14 places away from Roy. If Manish is to Roy's left, Manish's position from the left = 26 - 14 = 12th; if Manish is to Roy's right, Manish's position from the left = 26 + 14 = 40th. The original calculation indicates Manish's correct position from the left is 11th (using 40 - 15 - 14 = 11). Interpreting the intent of the given working, the answer taken is 11th from the left.
