ans is B

if x!=0, is 1/x>1 1. y/x>y 2. x^3>x^2

k not equal to 0. Is (ts/k)>0? STMT 1: k ^ 2 STMT 2: k> t + s ans: ts/k will be > 0 when ts>k when k2 is k2...ts>k so 1 is suff. 2: when k> t+s; lets take t= 5, s=9 and K=15, also ts>k but if t=5 and s=-9 and k=15 then ts ans is A

1 is sufficient as x is +ve and sqrt x is greater than y ;so x > y; x3 >y 2 is suff as x>y; x3>y
