Cost before and after the GST 
20081001 

From bruce: Hi, i seem confused on this topic:
If i need to add say 10% GST to a cost then i would times it by 1.1.
If i need to reduce the cost by 10% then i need to divide it by 1.1. that is all well and good.
What if i need to add 12%, 18% or 20% what is the formula then? Answered by Penny Nom.
