Dear student From the given statement; P sits on the bench I with his best friends & T is brother of R. We can clearly say that. P must be a boy as 'his' is used with reference to P. P sits with two others as 'best friends' is used to refer the other two persons. T is boy and R is girl. If P, T & S are sitting together then P and T are boys so S must be a girl. Regards Team TR
