I got <= also. The way I did it:
The possible values for n are: -1,0,1,2,3
For each value of n calculated 4-n.
So, LHS (left hand side) for -1,0,1,2,3 can be respectively (5,4,3,2,1)
Now which symbol between LHS and RHS (right hand side) holds true? Since LHS is 5 or lesser, that means the symbol has to be LHS <= RHS
Note this is not a DS question, but a PS question:
which of the following symbols should be substituted for ? to make both the above statements true for all integers n such that -2 < n <= 3
1. from statement 1, -2?n. Since -2 < n, ? is <
2. from statement 2, -1?n. From this, the only thing that may be established is ? is <=
3. hence, it seems to me that none of the symbols will make both statements true
But OA is <=
Not sure if I even understand this problem or approaching it correctly.
Thanks for any help.
