Introduction to Olympiad Chain Arithmetic
Olympiad Chain Arithmetic problems integrate multiple arithmetic concepts (AP, GP, SI, CI, percentages, ratios, time & work, etc.) into a single problem. These problems test your ability to apply multiple concepts sequentially and identify which concept applies at each step.
Prerequisites
How to Solve Olympiad Chain Arithmetic Problems
Step 1: Read the entire problem carefully to identify all concepts involved
Step 2: Break the problem into logical segments or stages
Step 3: Solve each stage using the appropriate formula/concept
Step 4: Pass the result from one stage as input to the next
Step 5: Keep track of units and intermediate values
Step 6: Verify intermediate results before proceeding
Step 7: Present the final answer
Example Problem
Example: In a GP, the 4th term is 32 (a=4, r=2). This amount is invested at 5% simple interest for 3 years. Find the interest earned. Solution: Step 1: GP term: a₄ = a × r³ = 4 × 2³ = 4 × 8 = 32 Step 2: Principal for SI = 32 Step 3: SI = (32 × 5 × 3)/100 = (32 × 15)/100 = 480/100 = 4.8 Answer: ₹4.80
