Akash said to Mohit, "That boy in blue shirt is younger of the two brothers of the daughter of my father's wife." How is the boy in the blue shirt related to Akash ?

The daughter of Akash's father's wife is the sister of Akash and brother of the daughter is the brother of Akash.

Now, let's understand the relationship between Akash and the individuals mentioned in the statement:

1. Daughter of Akash's father's wife: This refers to Akash's sister. Because Akash's father's wife is his mother, the daughter of his mother is his sister.
2. Brother of the daughter: This refers to the boy in the blue shirt, as he is one of the brothers of Akash's sister.

So, the boy in the blue shirt is indeed Akash's brother.
