Summary: International Trade and Currency Revision Weapons

Trade Balance: $X - M$
Total Trade: $X + M$
Normalized Trade Balance: $\frac{X - M}{X + M} \times 100$
Reverse Engineering: $X = \frac{Total Trade + Trade Balance}{2}$
$M = \frac{Total Trade - Trade Balance}{2}$
Tariff: $Rate \times Import Value$ (Never apply to exports).
Currency Chains: Multiply sequentially, treating rates as algebraic fractions to cancel units.

Secondary Sub-type.

Check Percentage Bases: "Among X, Y% are Z" means

Z = \frac{Y}{100} \times X

, not Grand Total.

Build Master Table: Use a grid with row and column totals to catch algebraic relationships.

Translate Constraints: Convert "more than", "only", and "twice as many" into strict inequalities or equations.

Enforce Integers: Remember that all final unit counts must be whole, non-negative numbers. Use this to eliminate impossible scenarios.

Production & Profit Cheat Sheet

Core Formulas

BOM Matrix: Rows = Products, Cols = Raw Materials
Unit Variable Cost: $\sum (Raw Material Qty \times Raw Material Price)$
Unit Contribution: $Selling Price - Unit Variable Cost$
Net Profit: $Total Contribution - Total Fixed Costs$

Optimization Rules

Scarce Resources: Calculate $\frac{Unit Contribution}{Scarce Resource Qty}$ and prioritize the highest ratio.
Multiple Constraints: Find the binding constraint first, optimize for it, and verify against secondary limits.
Fixed Costs: Deduct them exactly once from the total pool. Never mix them into unit variable costs.

Business, Trade, Finance and Market Data: Solved Questions with Step-by-Step Explanations (2 Problems)

Question 1 · Data Interpretation and Logical Reasoning MCQ

A country's Total Trade is $500$ billion and its Trade Balance is $100$ billion (surplus). What is the value of its Exports?

A.
$300$ billion
B.
$200$ billion
C.
$400$ billion
D.
$600$ billion

Correct Answer:

Step-by-Step Solution

Key idea: This is a reverse-engineering question, recognisable because it provides the aggregate metrics (Total Trade and Trade Balance) and asks for a specific component (Exports).

Step 1: Recall the relationships. Total Trade = $X + M$ and Trade Balance = $X - M$ .

Step 2: Add the two equations. $(X + M) + (X - M) = 2 X$ . Therefore, $2 X = Total Trade + Trade Balance$ .

Step 3: Substitute the given values. $2 X = 500 + 100 = 600$ .

Step 4: Solve for $X$ . $X = 300$ .

Answer: $300$ billion.

Question 2 · Data Interpretation and Logical Reasoning MCQ

In a trade conference, 5 delegates attend. Each delegate visits exactly 3 different exhibition halls. What is the total number of delegate-hall visits made?

A.
8
B.
15
C.
20
D.
24

Correct Answer:

Step-by-Step Solution

Key idea: This is a basic counting constraint question, recognisable because it gives the number of entities (delegates) and the number of actions per entity (visits per delegate), asking for the total actions.

Step 1: Identify the number of delegates: 5.

Step 2: Identify the number of visits each delegate makes: 3.

Step 3: Multiply the two to find the total number of visits. Total visits = $5 \times 3 = 15$ .

Answer: 15.
