Question

calculate the interest and the amount in the following cases . PRINCIPAL 250 RATE 7%TIME 4 years​

Answer 1

Answer:

Principal = RS. 250

Rate = 7%

Time = 4 Years

Step-by-step explanation:

Simple Interest = Principal * Rate * Time/100

Therefore,

= 250*7*4/100

= RS 70

Therefore Interest is RS 70

Amount = Principal + Simple Interest

Therefore,

= RS (250+70)

= RS 320.

Therefore Amount is RS 320..

Answers are RS 70 And RS 320...

Hope It Helps.....

Answer 2

➤ Given :-

Principle :- ₹ 250

Rate of interest :- 7%

Time :- 4 years

➤ To Find :-

Simple Interest and Total amount on the given sum.........

➤ Formulas required :-

Simple Interest :-

$\large \dashrightarrow \orange{ \boxed{ \tt \gray{ \frac{P \times R \times T}{100} }}}$

Total amount :-

$\large\dashrightarrow \orange{ \boxed{ \tt \gray{Simple \: Intrest + Principle}}}$

➤ Solution :-

Simple Interest :-

$\tt \longrightarrow \dfrac{250 \times 7 \times 4}{100}$

$\tt \longrightarrow \dfrac{ \cancel{250} \times 7 \times 4}{ \cancel{100}} = \dfrac{5 \times 7 \times 4}{2}$

$\tt \longrightarrow \dfrac{35 \times 4}{2} = \cancel \dfrac{140}{2} = \boxed{ \tt70}$

Now,

Total amount :-

$\tt \longrightarrow250 + 70$

$\tt \longrightarrow \sf Rs. \tt 320$

$\Huge\therefore$The simple interest is ₹ 70 and total amount is ₹ 320.

$\dashrightarrow$Some related formulas :-

Principle :- $\boxed{\tt\dfrac{SI \times 100}{R \times T}}$

Rate of interest :- $\boxed{\tt\dfrac{SI \times 100}{P \times T}}$

Time :- $\boxed{\tt\dfrac{SI \times 100}{P \times R}}$
