Dear Member,
In order or calculate the Minimum Wages the concept of NCR is not relevant.
The Minimum Wages is state oriented. Every state issues notification regarding updation of Minimum Wages (which can be on basis of industry, location, work category etc.)
However, in Delhi the Office Boy (if he is not doing any clerical job) will fall under "Unskilled" category. For which the current rate is Rs/ 13584/- (wef 01.04.2017).
