Introduction to Age + Other Topics
Age with Other Topics problems integrate age calculations with other quantitative topics like profit-loss, speed-distance, mixtures, and simple interest. These problems test cross-topic application skills.
Prerequisites
How to Solve Age + Other Topics Problems
Step 1: Identify the topics involved in the problem
Step 2: Extract age relationships first
Step 3: Extract other topic relationships
Step 4: Set up equations for each topic separately
Step 5: Look for connections between topics (common variables)
Step 6: Solve the combined system
Step 7: Verify all conditions from all topics
Example Problem
Example: A is 5 years older than B. A's age equals the selling price of an item bought for ₹100 at 20% profit. Find B's age. Solution: Step 1: Age relationship: A = B + 5 Step 2: Profit calculation: SP = CP × (1 + 20/100) = 100 × 1.2 = 120 Step 3: Given A = SP = 120 Step 4: B = A - 5 = 120 - 5 = 115 Answer: B = 115 years (unrealistic age - shows importance of checking)
Pro Tips & Tricks
- Profit: SP = CP × (1 + P%/100)
- Loss: SP = CP × (1 - L%/100)
- Speed: Distance = Speed × Time
- Mixture: (Quantity1 × Concentration1 + Quantity2 × Concentration2)/Total = Final Concentration
- Simple Interest: SI = P × R × T / 100
- Connect topics through age variables
