A sum of money amounts to ₹6,720 at simple interest
in 3 years at 12% per annum. What is the principal ?Solution
Let principal = P SI = (P × R × T) / 100 = (P × 12 × 3) / 100 = (36P) / 100 Amount = P + SI = 6,720 P + 36P/100 = 6,720 ⇒ (100P + 36P) / 100 = 6,720 ⇒ 136P / 100 = 6,720 ⇒ P = (6,720 × 100) / 136 ⇒ P = 6,72,000 / 136 = 4,800
