PT1: Tracing Exchange Rates on a Grid
Let us look at a visual exchange chart comparing foreign currency inputs to converted outputs. As you follow the arrow from USD to INR, the total value is calculated by multiplying the foreign amount by the conversion rate: \(100 \times 82 = 8200\). Visualizing this conversion line helps you see how exchange rates scale values up or down proportionally.
Part 1
PT2: Visualizing Commission Deductions
Look at a divided bar diagram representing your total exchange fund. The full length of the bar represents 100%. A small slice at the end, shaded in red, represents the bank’s 2% commission fee. The remaining 98% green bar represents the net amount that gets converted into foreign currency.
Part 2
PT3: The Bid-Ask Spread Diagram
Examine a visual balance scale comparing the Bid and Ask prices. The Bid price sits at 81 INR per unit and the Ask price sits at 83 INR per unit. A central gap highlighting the 2 INR difference illustrates the Bid-Ask spread. This visual gap clearly shows why buying and immediately selling currency results in a net operational cost.
