Question 1
If:
A = brother of, B = sister of, C = father of, D = mother of, E = son of, F = daughter of, G = husband of, H = wife of
Then what does 'Tarun C Isha and Isha E Manish' mean in terms of Tarun's relation to Manish?
C = 'father of', E = 'son of'. Combining: Tarun is father of Isha, and Isha is son of Manish. Therefore, Tarun is grandfather of Manish.
