Question

find the Simple interest and amount of 1250 for 5 years at.9%​

Answer 1

Answer:

given:

The Given Money = Rs. 1250

For = 5 years

At the rate = 9% p.a

To find :

The Simple Interest and amount

Solution :

Here,

Principal (P) = Rs. 1250

Time (T) = 5 years

Rate of Interest (R) = 9%

$★ \boxed{\sf{SI = \frac{Principal \times Rate \times Time}{100}}}$

$⟹SI= \frac{1250 \times 9 \times 5}{100}$

$⟹ SI = \frac{1125}{2} = 562.5$

The Simple Interest is Rs. 562.5

now, amount = simple interest + principle

= 562.5 +1250 = 1,812.5

∴ The Simple Interest is Rs. 562.5 and

amount = 1,812.5

Answer 2

$\sf \large \underbrace{ \underline{Understanding \: the \: Question}}$

Here we can see that principal , rate of interest and time for which principal is deposited is given and we have to find the Simple interest and amount which we can easily find by applying formula of Simple interest and to find amount we have to add interest in the principal.

‎ ‎ ‎ ‎ ‎ ‎

Before finding simple interest, we should understand what simple interest actually is!

‎ ‎ ‎ ‎ ‎ ‎

~Simple interest➠Simple interest is the interest which is calculated on the principal only.

So let's start!

‎ ‎ ‎ ‎ ‎ ‎

GIVEN:

⊙ Principal=Rs.1250

⊙ Rate of interest=9%

⊙ Time=5 years p.a.

TO FIND:

⊙ Simple interest

⊙ Amount

SOLUTION:

$\color{violet} \boxed{ \sf &#10029 \: Simple \: interest= \dfrac{P \times R \times T}{100}}$

‎ ‎ ‎ ‎ ‎ ‎

$\sf :\implies Simple \: interest= \dfrac{1250 \times 5 \times 9}{100}$

‎ ‎ ‎ ‎ ‎ ‎

$\sf :\implies Simple \: interest= \cancel\dfrac{1250 \times 5 \times 9}{100}$

‎ ‎ ‎ ‎ ‎ ‎

$\large \color{pink}\boxed{\sf :\implies Simple \: interest= Rs.562.5}$

‎ ‎ ‎ ‎ ‎ ‎

▬▬▬▬▬▬▬▬▬▬

$\color{lightblue} \boxed{&#10029 \sf Amount=Simple \: interest+Principal}$

‎ ‎ ‎ ‎ ‎ ‎

$\sf :\implies Amount = 562.5 + 1250$

‎ ‎ ‎ ‎ ‎ ‎

$\color{blue} \large \boxed{\sf :\implies Amount = 1812.5}$

‎ ‎ ‎ ‎ ‎ ‎

Hence the final answers are:-

• Simple interest=Rs.562.5
• Amount=Rs.1812.5
