Answer:

10% per annum

Step-by-step explanation:

Amount (A) = Rs.13,310

Principal (P) = Rs.10,000

Time (n) = 3 years

Let the rate of interest be R.

A = P (1 + R/100)ⁿ

=> 13,310 = 10,000 (1 + R/100)³

=> 1331/1000 = (1 + R/100)³

=> (11/10)³ = (1 + R/100)³

=> 11/10 = 1 + R/100

=> R/100 = 11/10 - 1

=> R/100 = 1/10

=> R = 10% per annum
