Answers and Explanations
Explanation [1-5]-
Persons – A, B, C, D, E and F
Years – 1978, 1982, 1995, 1997, 2013 and 2015
Now draw family tree using following notations:

Age is calculated according to the year 2018

1. There is a difference of 18 years between the ages of D and A.D is the father of A. Ais the son of C.
Hence, age of D is 23 years and born in the year 1995 and age of A is 5 years and born in the year 2013. C is wife of D.

2. B is younger than C. E is not the oldest person of the family. B is the only granddaughter of the mother of D.
Hence, B is daughter of C. E is mother of D and F is father of D.

3. Father of D is 4 years older than D's mother.
Hence, F is 40 years old years old and born in the year 1978 and E is 36 years old and born in the year 1982.
C is 21 years old and born in the year 1997 and B is 2 years old and born in the year 2015.

Eight friends C, D, E, F, L, M, N and O are seated in a straight line, but not necessarily in the same order. Some of them are facing north while some face South. Only three people sit to the right of M. E sits second to the left of M. F sits third to the right of O. O is not an immediate neighbour of M. O does not sit at any of the extreme ends of the line. Both the immediate neighbours of O face south.
D sits second to the right of N. As many people sit between M and D as between M and L. Immediate neighbours of F face opposite directions(i.e., If one person faces north then the other person faces south and vice-versa). C faces south. L and F face direction opposite to C.(i.e If C faces north then both L and F face south and vice-versa)

Answers and Explanations
1. Answer - Option A
Explanation -

AB = [latex]\sqrt{{14}^{2} + {6}^{2} } = 2 \sqrt {58}[/latex] m
2. Answer - Option D
Explanation -

[latex]\sqrt{{9}^{2} + {3}^{2} } = 3 \sqrt {10}[/latex] m
3. Answer - Option A
Explanation -
For this, start from back:
She is walking in west and before that she turned to her right, so she must be travelling in south before turning right.
Now she was walking in south and before that she turned to her right, so she must be travelling in east before turning right.
Now she was walking in east and before that she turned to her left, so she must be travelling in south before turning left.
Now she was walking in south and before that she turned to her right, so she must be travelling in east before turning right.
Now she was walking in east and before that she turned to her left, so she must be travelling in south before turning left.
At last south direction.
