According to the given information,

Number of students in the class = 16 + 13 - 1

= 29 - 1

= 28

Hence, “28” is the correct answer.

Option C is correct.

Aman is 22^nd from the top and Sajid is 5 ranks below Aman.

So, Sajid is 27^th from the top. Also, Sajid is 34^th from the bottom.

Number of students passed = (27+34)-1 = 60

Let the number of students passed = 3x

Number of students failed = 2x

⇒ 3x = 60

⇒ x = 20

⇒ 2x = 40

Total number of students = 60 + 40 = 100

1. Yuvraj has got more marks than Shakti.

Yuvraj > Shakti = Anamika

2. Neha has got less marks than Anamika.

Anamika > Neha

3. Swapnil has got more marks than Adil.

Swapnil > Adil

4. Yuvraj gets less marks than Adil.

Adil > Yuvraj

5. Anamika and Shakti has got equal marks.

Anamika = Shakti

6. Aditya has got more marks than Adil but less than only one person in the group.

___ > Aditya > Adil

On combining all the six statements together, we get:

Swapnil > Aditya > Adil > Yuvraj > Shakti = Anamika > Neha

Hence, ‘Swapnil – highest, Neha – lowest’ is the correct answer.

Option C is correct.

1. Five girls took part in a race.

2. Rajni finished before Mahika but behind Garima.

Garima > Rajni > Mahika

3. Ashmita finished before Sanchali but behind Mahika.

Mahika > Ashmita > Sanchali

Combining (2) and (3), we get:

Garima > Rajni > Mahika > Ashmita > Sanchali

Hence, ‘Rajni’ came second in the race.

Option D is correct.

Deepak ranks 26^th and Bharat is 8 ranks ahead of Deepak. So, Bharat ranks 18^th .

Number of students behind Bharat in rank = (42-18) = 24

So, Bharat ranks 25^th from the last.
