Beginner lesson

Money choices get clearer when you compare per-unit prices and know how interest grows.

  1. Needs before wants.
  2. Compare price per unit, not per pack.
  3. Save a fixed share first.
  4. Rule of 72: 72 ÷ rate ≈ years to double.
Worked example: ₹60 for 3 pens vs ₹90 for 5: ₹20 vs ₹18 each — the 5-pack is cheaper per pen.
