alone - both are clearly insufficient because they dont talk about the other set.danjuma wrote:5. X and Y are sets of positive integers. Is the greatest integer in X greater than the greatest integer in Y.?

together:
x {1,3,5,7,9,11,13,15,17,19} i know we only need 5 but these are ALL the posibilities.
y{0,2,4,6,8,10,12,14,16,18}
x could be from 1-9 and y could be from 14-18 and the greater integer in x would not be the greatest.
or x can be 11-19 and y 14-18 and here the greatest integer is bigger.
