Answer 1

Answer:

Rs.37,500 should be given at an interest of 12% p.a. to get a Simple Interest of Rs.9,000.

Step-by-step explanation:

The formula for Simple Interest is

SI=$\frac{Principal*Rate*Time}{100}$

Given,

Rate=12% p.a., SI= Rs.9000 and Time=2years

To find Principal(the money to be lent so as to get SI of 9000)

Substituting the values in the given formula,

9000=$\frac{P*12*2}{100}$

⇒9000=P×$\frac{24}{100}$

⇒P=9000×$\frac{100}{24}$

⇒P=9000×4.2

⇒P=37500

Answer 2

$\huge{ \purple{ \bold{ \star \: \: {answer}}}}$

$\large{ \sf{ \underline{Given}}}$

Rate:- 12% p.a

interests:- Rs 9000

Time:- 2yrs

$\large{ \underline{find}}$

principal amount:- ?

$\large{ \underline{ \bold{soulution}}}$

[simple interest can be calculated by the formula]

$\large{ \pink{ \boxed{ simple \: interest = \frac{p \times r \times t}{100}}}}$

{keeping the formula}

$\large{p.a = s \: t \: \frac{100}{rt}}$

$\large{ \frac{9000 \times 100}{(2 \times 12)}}$

$\large{ \green{ \boxed{ principal \: amount = 37500}}}$

$\large{ \orange{hence \: the \: principal \: amount \: that \: granted \: given \: interest \: = 37500}}$

hope its help u
