Question

12. If Shalini pays an interest of * 96 for 3 years
on a sum of * 800, find the rate of interest
​

Answer 1

Answer:

4%

Step-by-step explanation:

Given In the Question :

Interest = Rs 96

Time = 3 years

Sum (Principal) = Rs 800

To find Rate of Interest

Applying Formula :

\sf \: R = \dfrac{S.I \times 100}{P \times T }R=

P×T

S.I×100

Putting Values :

\sf \: R = \cancel \dfrac{96 \times 100}{ 800 \times 3}R=

800×3

96×100

\boxed{\boxed{Rate\:= 4\%}}

Rate=4%

Verification:

Principal = Rs 800

Rate = 4%

Time = 3 years

\sf \: S. I = \dfrac{P \times R \times T}{100}S.I=

100

P×R×T

\sf \: S.I = \dfrac{800 \times 4 \times 3}{100}S.I=

100

800×4×3

\sf \: S.I = \cancel\dfrac{9600}{100}S.I=

100

9600

\boxed{\boxed{Rs\:96}}

Rs96

Which Is given as Interest

Hence,Answer is Correct

Answer 2

Rate=4%

$\bf\green{Given~In~the~Question-}$

Interest = 96Rs

Time = 3 years

Sum (Principal) = 800Rs

$\bf\blue{To~find~Rate~of~Interest=?}$

$\bf\red{Applying~Formula -}$

$\sf \: R = \dfrac{S.I \times 100}{P \times T }$

$\bf\orange{Putting~Values -}$

$\sf \: R = \cancel \dfrac{96 \times 100}{ 800 \times 3}$

Rate=4%

$\bf\pink{Verification -}$

Principal = 800Rs

Rate = 4%

Time = 3 years

$\sf \: S. I = \dfrac{P \times R \times T}{100}$

$\sf \: S.I = \dfrac{800 \times 4 \times 3}{100}$

$\sf \: S.I = \cancel\dfrac{9600}{100}$

$\bf\pink{Interest = 96Rs}$
