Present value = Rs.6250 Show
Interest rate = 8 % per annum Time = 1 years ∵ Interest is compounded half-yearly. ∴ Amount (A) = P [1 + (R/2)/100]2n [Where, P = Present value R = Annual interest rate n = Time in years] ∴ A = 6250 [1 + (8/2)/100]2 ⇒ A = 6250 [1 + 4/100]2 ⇒ A = 6250 [26/25]2 ⇒ A = 6250 × 26/25 × 26/25 ⇒ A = 10 × 26 × 26 ⇒ A = 6760 ∴ Amount = Rs.6760 ∴ Compound interest = Rs.(6760 – 6250) = Rs.510 ∴ Divakaran gets a CI of Rs.510.
