Answers & Solutions:

1) Answer (B)

Saurav is ranked 274th from the first, so there are 273 students ahead of him.
Saurav is ranked 367th from the last, so there are 366 students behind him.
Total number of students in the class = 366 + 273 + 1 = 640
Hence option B is the correct option.

2) Answer (B)

According to given condition, class of 120 students has 80 boys and 40 girls. If Ramu was ranked 25th from first there are 24 students before him out of which 10 are girls, so remaining 14 students must be boys. So Ramu is the 15th boy from the top. Number of boys behind him is 80-15 = 65
Hence option B is the correct option.

3) Answer (C)

Let the total strength of the class be ‘x’
He scored more than at least 75% of the class.
So his rank can be atmost in the top 25% of the class.
In that case we get,
0.25x = 20 => x = 80
Hence the strength of the class is at least 80.
Hence Option C.

4) Answer (D)

Let the total number of students in the class be ‘n’
Arjun’s rank is 16. This means that he scored more than (n-16) students of the class.
So we get,
$\frac{n-16}{n}=\frac{75}{100}$
$n=64$
Thus the strength of the class is 64.
Hence Option D.

5) Answer (D)

We know that if a person’s position in a queue is x from the front and y from the last, then the total number of people in the queue is x+y-1.
There are two cases possible here.
Case 1: Shyam’s rank is better than Ram’s
Ram’s rank =35+25+1 = 61
Total number of people = 61+25-1 = 85
Case 2 :Ram’s rank is better than Shyam’s
Ram’s rank = 35-(25+1) = 9
Number of people in class = 9+25-1 =33
But this is not possible as Shyam’s rank is 35

6) Answer (E)

Here, the position of Anil is not clearly mentioned.
Anil can be in the front of Naveen or behind Naveen.
His rank can be 30 or 32
Hence, cannot be determined.

7) Answer (B)

We know that if a person’s position in a queue is x from the front and y from the last, then the total number of people in the queue is x+y-1.
Now, A’s rank is 45 and there are 20 people between A and B.
Case 1: If A’s rank is better than B, then B’s rank would be 45+(20+1) = 66 which is 15th from the last.
=> Number of people in the class = 66+15-1 = 80.
Case 2: If B’s rank is better than A, then B’s rank would be 45-(20+1) = 24 which is 15th from last.
=> Number of people in the class = 24 + 15 – 1 = 38 which is not possible as A’s rank is 45.
So, this case is not possible.
Thus, 80 is the correct answer.

8) Answer (E)

A got more than 2 students so A must be 5th. Similarly, C must be 4th. B and D did not get 1st rank and E and F are ranked lower than G. Hence G must be having the first rank. E has more marks than B and D. So E must be second. B and D will occupy 3rd and 6th position. F will be last. We cannot exactly determine who will occupy 3rd and who will occupy 6th. Hence, the correct answer is cannot be determined.

9) Answer (E)

Since we do not know how many people he crossed when he scored 10 more marks, we cannot ascertain the total number of people who appeared in the exam. However, we can ascertain the minimum number of people appeared. If we assume that there were 0 students in the 10 marks range, then the number of people who appeared in the exam would have been (43+23-1 =) 65.
But, we cannot ascertain the exact number. So, E is the correct answer.

10) Answer (A)

There are 12 people before Q, => Let us assume Q is at 13th position from left end.

There are 15 people between Q and S, => S is at 29th position.

There are 4 people between P and Q, => P can be either at 8th or 18th position from left.

There are 8 people between S and R, => R is at 20th position.

Thus, there are minimum of 29 people in the row.

=> Ans – (A)

11) Answer (C)

A is sitting towards immediate left of B and immediate right of C, => CAB

C is sitting to immediate right of F, => FCAB

D is immediate right of E who is to the left of F, => EDF

Thus, final arrangement is :

$\therefore$ F and C are sitting in the center.

=> Ans – (C)

12) Answer (A)

Aman’s rank from top = 10th

Aman’s rank from bottom = 12th

=> Total number of people = $(10+12)-1=22-1=21$

=> Ans – (A)

13) Answer (A)

Since only neighbour of C is B, C is in the extreme and there are 2 people between B and D. So on D must sit in the other extreme.
We get the following arrangement –

Hence, option A is the right choice.

14) Answer (D)

Consider the 1st rank from the top. This rank from the bottom is 37. We can see that the sum of the ranks from the top and bottom = 38
So, every odd rank from the top has an odd rank from the bottom too. (Since 38 is even).
Number of odd numbers less than or equal to 37 = 19
So, 19 students have ranks that are odd both from the top and the bottom.

15) Answer (D)

The two ranks from the top are 23 and 28. So, the ranks from the bottom are 67 – 23 + 1 and 67 – 28 + 1 = 45 and 40 respectively.
