If y is not equal 0 and y is not equal -1, which is greater, x/y or x/(y+1)?
(1) x is not equal 0
stem(1) we just know x (no sufficiency)
stem(2) we can not know the value of x and y (no sufficiency)
together (1) and (2): we can know, which is greater, x/y or x/(y+1)
please tell me why I am wrong
Each person on a committee with 40 members voted for exactly one of 3
candidates,F,G or H. Did Candidate F receive the most votes from the 40 votes cast?
(1) Candidate F receive 11 of the votes
(2) Candidate H received 14 of the votes
stem(1) we can not know the number of G and H (no sufficiency)
stem(2) we can not know the number of F and G (no sufficiency)
together (1) and (2) F=11 G=15 H=14 (sufficiency)
