B) 1,2 and 3 Mk Utkarsh answered Apr 21, 2018 Mk Utkarsh comment Share Follow See all 3 Comments See all 3 3 Comments reply Akhilesh Singla commented Apr 21, 2018 i edited by Akhilesh Singla Apr 22, 2018 reply Follow Share I think it is data insufficient because the gender of S is unknown. They haven't declared P and T are the "only" daughters of X. We can't make any judgement with the given data because no absolute idea has been given about gender of S. 0 votes 0 votes Lionel Messi commented Apr 22, 2018 reply Follow Share Yep u are right its data insufficient as no of brothers was asked not children. 0 votes 0 votes Akhilesh Singla commented Apr 22, 2018 reply Follow Share I didn't notice the mistake in the question posted before. You are right, they asked number of boys of X, not total children. That's why gender requirement came in. 0 votes 0 votes Please log in or register to add a comment.
