my question is how can i get the COST of an item if then given is the Net and the GST?

The basic equation is:

net = cost + (gst * cost) = cost * (1.0 + gst)

(with gst expressed as a decimal)

Therefore by algebra (dividing both sides by 1.0 + gst) you have:

cost = net / (1.0 + gst)

Or to make it really obvious, `cost = net / 1.1` when gst is 10% – joshuahealy Apr 11 '12 at 02:34
