TRY IF U CAN

He had a sister. So the sisters only brother died.

I DIDNT GET IT.......

SIR..... WRONG ANSWER...... ANSWER IS IN QUESTION ONLY READ IT CAREFULLY

the chartered accountant brother died means the CA  was only son of his parents

ractify me if i am wrong

There was one brother and one sister. So sister's brother died i. e. the brother died.

NO YAAR U ARE WRONG.........

SIR IF U DONT MINE.... WHO IS BROTHER WHO IS SISTER...........????

a CA brother had died, it means CA man has died& he may not have not any brother.

ca ca bhai bhai..

THE CA BROTHER WAS DIED WHO HAS NO BROTHER MEANS THE CA HIMSELF DIED

RACTIFY ME IF WRONG

NO YAAR IT IS WRONG.....

That CA is female and her brother is died, so the person who died have no brother but CA (a female) had brother which is died

(and they are brother and sister only, they dont have any more brother or sister)

Suppose X & Y are brothers and sisters respectively. So here X died who is brother of Y. So X did not have a brother but Y's brother died.

u both right  sir  i.e aditya nd mukesh
