Any HR/Tax Gurus out there?

[Tricky]

If I pay £200 out of my monthly wage (after tax so net)
How much is the £200 worth Gross (before tax) if I pay tax at 40% :dunce:

Any ideas? - Nice to see how you got to the value also (not asking much!) :erm:

The £200 is 59% of your Gross salary as you have paid 1% NI and 40% tax.

200 *100/59 = £338.98
