(B) 6%
(C) 6.5%
(D) 8%​

Answer 1

Answer:

The rate willl be 6% per year

Answer 2

Answer:

(B) 6%

Step-by-step explanation:

In quention , we have the values of

Principle value= Rs.7500

Time (n) = 2 years

Compound interest = Rs.927

Now, we the the formula of compound interest

$principle value + compound interest= principle value (1+\frac{rate}{100} )^n$

Now, putting the all values of given data in the above formula

$7500+927= 7500 (1+\frac{r}{100} )^2\\\dfrac{8427}{7500} =(1+\frac{r}{100} )^2\\\\\frac{2809}{2500} = (1+\frac{r}{100} )^2$

Now take square root of both side, we get

$\frac{53}{50} =(1+\frac{r}{100})$

On solving the equation, we get

$\frac{53}{50} -1= \frac{r}{100} \\\\\frac{3}{50} *100 + r$

Hence,

r = 6 %
