Answer 2

Answer:

the rate of interest is 15%

Step-by-step explanation:

Since we have given that

Amount in 2 years = Rs. 5290

Amount in 3 years = Rs. 6083.50

So, it becomes,

6083.50/5290 =  (p * 1 + r/100)^3/ (p*1 + r/100)^3

1.15 = 1+r/100

0.15 *100 =r

r=15%

Hence, the rate of interest per annum is 15%.
