Question

In how many years will ₹ 4,000 amount to ₹ 5,324 at the rate of 10%
per annum compounded annually?​

Answer 1

Answer :

3 yeras

Explanation :

Principal (P) = ₹4,000

Rate of compound interest (r)= 10 % per annum

Amount (A) = ₹5,324

Time (years) = ?, say, t years

Now, A = P (1 + r / 100)^ t

So, 5,324 = 4000 * ( 1 + 10/ 100)^ t

Or, 5,324 = 4,000 * ( 1.1)^ t

Or, (1.1) ^t = 5,324 / 4,000 = 1.331

We know that 1.331 = (1.1)^3

So, (1.1)^t = (1.1)^3

Or, t = 3 years.

Answer 2

Answer:

400/100 x 100=4400

4400/100 x 100=4840

4840/100 x 110=5324
