New Wage lrate as per budget 21

Hi,

I would like to know how the new wage rule needs to be calculated?
For eg. if the skilled employee needs to be paid @ Rs. 784 wef 1/4/2021…

This needs to be multiplied with 30 days or number working days like 24 or 26 days?

Secondly, The multiplied total should be minimum in basic or it can be gross income?

Kindly clarify.
