Answer 1

Step-by-step explanation:

(1) 13310 rupay

(2) 10 percent

Answer 2

The amount is Rs. 13310 and the rate of interest is 10%

Step-by-step explanation:

Principal = 10000

Interest = 3310

Amount = Principal +interest

Amount = 10000+3310

Amount = 13310

Time = 3 years

Formula : $A=P(1+r)^t$

$13310=10000(1+r)^3$

$\frac{13310}{10000}=(1+r)^3$

$\sqrt[3]{\frac{13310}{10000}}=(1+r)$

$\sqrt[3]{\frac{13310}{10000}}-1=r$

$0.1 = r$

$10\% =r$

Hence The amount is Rs. 13310 and the rate of interest is 10%
