Answer 1

Answer:

Given:

Principal=₹4000

Amount=₹4410

Time=2years

To find:

The rate percent if compounded anually.

Solution:

Formula to be used:-

$\fbox{A}={P}(\frac{1+r}{100})^{2}$

$\longrightarrow{4410}=4000\frac{1+r}{100}^²$

$\longrightarrow{4410}=4000×\frac{100+r}{100}^²$

$\longrightarrow\frac{4410×100×100}{4000}=(100+r)^²$

$\longrightarrow{11025}=(100+r)²$

$\longrightarrow(100+r)=\sqrt{11205}$

$\longrightarrow{100+r}=105$

$\longrightarrow{r}=105-100$

$\longrightarrow{r}=5$

Therefore,The rate percent is 5% if, compounded anually.

Answer 2

Answer:

Principal=34000

Amount=4410

Time=2years

To find:

The rate percent if compounded anually.

Solution:

Formula to be used:

A = P()2 100

+ 4410 = 4000 00

+ 4410 = 4000 x 100+r? 100

- 4410x 100 x 100 = (100 +r)* 4000

11025 = (100+ r)2

+ (100 +r) = v11205

100 + = 105

-r = 105 - 100

+ r = 5

Therefore,The rate percent is 5% if, compounded anually.
