1.Blood relation questions Introduction type
In this type of questions one person introduces another.

To solve this type of question break the sentence at "is" and resolve two sides separately and equate to get the final answer.
Resolving at "is" we get two halves , "His brother's father" and "the only son of my grand father"
Left half-His brother's father ->His father
Right-the only son of my grand father->Father(Diya's father).
His father=Diya's father.
So,answer is "Diya is the sister of Rajesh"
Eg2: Tom introduces Riya as the daughter of the only son of my father’s wife. How is Riya related to Tom?
Give question is same as Tom introduces Riya."Riya is the daughter of the only son of my father’s wife".So while solving this kind of problems break the sentence at "as".
Left half-Riya.
Righthalf-daughter of the only son of my father’s wife.
Resolve the right half from right to left
my father’s wife->mother
the only son of mother->Tom himslef
Daughter of Tom->daughter
Riya=daughter
So answer is Riya is the daughter of Tom
