Formulas
Marked Price (M) = Cost Price (C) + 40% of C = 1.4 * C
Selling Price (S) = Marked Price - 10% of Marked Price = 0.9 * M = 1.26 * C
Gross Profit = Selling Price - Cost Price = 1.26 * C - C = 0.26 * C
Tax on Gross Profit = 10% of Gross Profit = 0.1 * 0.26 * C
Net Profit = Gross Profit - Tax = 0.234 * C
