Tds on commission

The case is as follows:

We are to pay commission to our consultant for  execution of an event. Want to know how to deduct TDS

Point - 1) The client pays us Rs.100/-

Point - 2 )The client deducts 10% as TDS, so we get Rs.90/-

Now we consultant is entitled for 50% profit , that is  from Rs.100/-

So should pay him Rs.50/- less 10%TDS as per point no - 1

or

Rs.45/- less TDS as per point no - 2

Thanks
