Let Rs. p be the principal amount
Simple interest for 6 years = (p × 12 × 6)/100
Simple interest for 12 years = (p × 12 × 12)/100
∴ Required ratio = (p × 12 × 6)/100 : (p × 12 × 12)/100 = 6 : 12 = 1 : 2
Simple interest for 6 years = (p × 12 × 6)/100
Simple interest for 12 years = (p × 12 × 12)/100
∴ Required ratio = (p × 12 × 6)/100 : (p × 12 × 12)/100 = 6 : 12 = 1 : 2
