The simple interest on a sum of money for 3 years at 5% per annum is 1000. What will be thecompound interest on that sum at the same rate and for the same period? |
|
Answer» <P>Answer:
Step-by-step explanation: Given that: To Find:
Formula used:
Where,
First we have to find the principal: ⟶ S.I. = (P × R × T)/100 Substituting the values. ⟶ 1000 = (P × 5 × 3)/100 ⟶ 1000 = 15P/100 ⟶ 15P = (1000 × 100) ⟶ P = 100000/15 ∴ Principal = Rs 100000/15 = Rs 6666⅔ Finding the compound interest: ⟶ C.I. = P(1 + R/100)ᵀ - P Substituting the values. ⟶ C.I. = 6666⅔(1 + 5/100)³ - 6666⅔ ⟶ C.I. = 6666⅔(1 + 0.05)³ - 6666⅔ ⟶ C.I. = 6666⅔(1.05)³ - 6666⅔ ⟶ C.I. = 6666⅔ × 1.157625 - 6666⅔ ⟶ C.I. = 7717.5 - 6666⅔ ⟶ C.I. = 1050.83 (APPROX.) ∴ Compound interest = Rs 1050.83 |
