Multi-Generation Tree

Multi-Generation Tree problems involve age relationships across three or more generations (grandparents, parents, children). These problems test understanding of generational age gaps and family structures.

Introduction to Multi-Generation Tree

Prerequisites

Age difference concepts Generational gap understanding Linear equations Family relationship logic

Why This Matters: These problems appear in 1-2 questions in banking mains and SSC. They test ability to handle complex family relationships.

How to Solve Multi-Generation Tree Problems

Step 1: Identify all generations and family relationships

Step 2: Start from the youngest generation

Step 3: Express older generations' ages in terms of younger ones

Step 4: Use typical generation gaps (25-35 years) when not specified

Step 5: Set up equations based on given relationships

Step 6: Use sum of ages or other conditions to solve

Step 7: Verify all ages are biologically possible

Pro Strategy: Always express all ages in terms of the youngest person's age. Use typical generation gaps (25-35 years) as sanity checks.

Example Problem

Example: A grandfather is 4 times as old as his grandson. The father is 30 years older than the son. The sum of all three ages is 110 years. Find each age. Solution: Step 1: Let grandson = x, father = x + 30, grandfather = 4x Step 2: Sum: x + (x+30) + 4x = 6x + 30 = 110 Step 3: 6x = 80 → x = 13.33 (not integer - adjust) Try x=13: sum=6×13+30=78+30=108 x=14: 84+30=114 So x=13.33 exactly → 13 years 4 months if exact. Typically ages given as integers, so adjust numbers.

Pro Tips & Tricks

Typical parent-child age difference: 25-35 years
Typical grandparent-grandchild difference: 50-70 years
Grandparent is parent of parent
Generation gap = (Grandparent - Grandchild)/2 approximately
Express older in terms of younger to minimize variables
Check that parent is older than child and younger than grandparent

Shortcut Methods to Solve Faster

If G3 = x, G2 = x + d1, G1 = x + d1 + d2

Sum = 3x + 2d1 + d2 (for one person per generation)

Average age ≈ (G1 + G2 + G3)/3

Common Mistakes to Avoid

Incorrect generation gaps (too small or too large)

Missing that grandparents are parents of parents

Not verifying that all ages are positive and realistic

Forgetting that age differences remain constant
