ReplyDeleteNotice that the LENGTH statement in the SELECT group has not been specified. Remember that without the LENGTH statement, values for Group might be truncated, as the first value for Group (London) is not the longest possible value.
ReplyDeleteSo, the answer is B.

ReplyDeleteset sashelp.class(keep=name age);
if age>=13 then group='Teen';
if 11<=age<=13 then group='Pre-Teen';
run;
what is the output if age is 13
pre teen
Deletepre teen
DeletePre-

Ans is D;
ReplyDeleteWhich one of the following is the value of the CITY variable?
in ques. City variable mention as CITY & variable name would be case sensitive
The ans would be B. Copenh.
DeleteBecause length of a variable is assigned to PDV as per its first appearance. And so variable (city) will have a length of 6 characters(because london has 6 characters).
D for sure
