@kanak jiya,
u may confused...... 'md' & 'mkdir' both are used on Windows........ in LINUX/UNIX only 'mkdir' is used to create directory.

question 10 seems to be wrong

There is no correct ans for Q15 .. ls|wc -l will not always give correct count.. correct option should be "ls -l|wc -l " as ls command without options may display multiple files on single line.
