Find the compound interest on Rs 7000 for 3 years at 5% per annum, compounded annually.

Answer :

Final answer:

The compound interest on Rs 7000 for 3 years at 5% per annum compounded annually is approximately Rs 1102.50.

Explanation:

To find the compound interest on Rs 7000 for 3 years at 5% per annum compounded annually, we can use the formula:



Compound Interest = P(1 + r/n)^(nt) - P



Where P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years. Plugging in the values given:



Principal amount (P) = Rs 7000
Annual interest rate (r) = 5%
Number of times interest is compounded per year (n) = 1
Number of years (t) = 3



Compound Interest = 7000(1 + 0.05/1)^(1*3) - 7000



Simplifying the equation, we get:



Compound Interest = Rs 7000(1.05)^3 - Rs 7000



Calculating this, we find that the compound interest on Rs 7000 for 3 years at 5% per annum compounded annually is approximately Rs 1102.50.
