In this formation, the first number in the first column is getting multiplied by the number in the third column and the resultant number is being added to the number in the second column to give the number in the fourth column.

First row 6 × 2 + 8 = 20,

Second row 7 × 4 + 2 = 30,

Fourth row 5 × 9 + 5 = 50

Therefore, third row 8 × 6 + 7 =**55**,

Hence, option A is correct.

First row 6 × 2 + 8 = 20,

Second row 7 × 4 + 2 = 30,

Fourth row 5 × 9 + 5 = 50

Therefore, third row 8 × 6 + 7 =

Hence, option A is correct.

Number of students between Sohan and Mohan = 45 – ( 8 + 10 ) = 27

Clearly, there are 27 students between Sohan and Mohan. It's further given that Rohan's position is exactly between the two.

∴ Rohan's position = |
Total no. of students between Sohan and Mohan + 1 | |

= | 27 + 1 | = 14 |

Therefore the number of students between Rohan and Mohan is 13, and on counting, Rohan's position will be 14th from Mohan.

So, Rohan's position is 14th from Mohan.

Hence, option A is correct.

So, Rohan's position is 14th from Mohan.

Hence, option A is correct.
