The Sale Price SP of the phone, i.e. it's Original Price OP(sale price excluding GST) + GST on it, is $8800:

SP = OP + GST ---(1)

But we don't have the GST, we only have it's percentage. So let's calculate out GST from the percentage/rate:

GST-in-Percentage = (GST / SP) * 100 => 10 = (GST / 8800) * 100 => GST = 880

Now, putting values in (1):

8800 = OP + 880 => OP = 8800 - 880 => OP = 7920

Note: I have seen it again and again, but I can't see anything wrong with the approach. But this is how they did it:

Price of the mobile = 8800 GST rate = 10% Original Price=? Price percent of the mobile = 100% + 10%; By using Unitary method, 110% price = $8800 1% price = (8800 / 110) 100% price = (8800 / 110) * 100 = $8000 So the original price is $8000.
