Question

Calculate the simple interest on a principal amount
of 8,000 for 3 years at a rate of 9% pa
​

Answer 1

Answer:

Simple interest = ₹2160

Step-by-step explanation:

Given :

Principal = ₹8,000

Time = 3 years

Rate = 9% pa

To find :

The simple interest

Taken :

To find the simple interest use this formula -:

$\boxed{\rm{S.I.=\dfrac{P\times T\times R}{100}}}$

Where,

S.I. = Simple interest

P = Principal

T = Time

R = Rate

Solution :

$:\implies\displaystyle\rm{S.I.=\dfrac{8,0\cancel{00}\times3\times9}{1\cancel{00}}}$

$:\implies\displaystyle\rm{S.I.=80\times3\times9}$

$:\implies\displaystyle\rm{S.I.=240\times9}$

$:\implies\displaystyle\rm{S.I.=Rs.2160}$

So , the simple interest is ₹2160 .

Answer 2

Answer:

$\boxed{\huge{ \boxed{ \underline{ \underline{ \sf{SI= ₹2160}}}}}}$

Step-by-step explanation:

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{\pink{Given}}}}}}}}$

• $\longrightarrow$Principal = ₹8,000

• $\longrightarrow$Time = 3 years

• $\longrightarrow$Rate = 9 %

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{\pink{To\:Find}}}}}}}}$

• $\longrightarrow$Simple Intrest [SI]

$\huge{ \boxed{ \boxed{ \underline{ \underline{ \textsf{ \textbf{\pink{Solution}}}}}}}}$

We know that :-

• $\boxed{ \boxed{ \underline{ \underline{ \sf{S.I = \frac{PRT}{100}}}}}}$

Where

• $\longrightarrow$P = Principle

• $\longrightarrow$R = Rate

• $\longrightarrow$T = Time

• $\longrightarrow$SI=$\bf \frac{8000\times 9 \times 3}{100}$

• $\longrightarrow$SI = $\bf \frac{80 \cancel0 \cancel0\times 9 \times 3}{1 \cancel0 \cancel0}$

• $\longrightarrow$SI = 80 × 9 × 3 = ₹2160
