1. Find the amount received when Rs. 7000 is invested at 9% per annum for a period from February 4, 2014 to April 18,2014

$\underline{\underline{\maltese\:\:\textbf{\textsf{Given}}}}$

${ \frak{ \underline \purple{principal \: = \: rs \: 7000}}}$

${ \frak{ \underline \purple{ Rate\: = \: 9 \: percent \: per \: annum}}}$

$\underline{\underline{\maltese\:\:\textbf{\textsf{Find}}}}$

1. Amount (A) ⟶ ?

$\underline{\underline{\maltese\:\:\textbf{\textsf{Solution}}}}$

The number of days for which the money is borrowed are counted as :-

Months: February , March , April

Days: 25 , 31 , 17

$⟶ T = 25 + 31 + 17 \: days =73 \: days = \dfrac{73}{365} \: years = \dfrac{1}{5} \: years$

$⟶ S.I = \dfrac{P ×R × T }{100}$

$⟶ \dfrac{7000 \times 9 \times 1}{100 \times 5}$

•°• We got the simple interest as Rs.126

Now let's find out amount

•°• Required amount = P + S.I = rs. 7000 + rs. 126 = rs. 7126

Amount (A) ⟶ ?

$\huge\underline{\underline{\dag\:\:\textbf{\textsf{\green{Solution}}}}}$

The number of days for which the money is borrowed are counted as :-

Months:- February , March , April

Days:- 25 , 31 , 17

$\rm{\implies T = 25 + 31 + 17 \: days =73 \: days = \dfrac{73}{365} \: years = \dfrac{1}{5} \: years}$

$\implies S.I = \dfrac{P ×R × T }{100}$

$\implies \dfrac{7000 \times 9 \times 1}{100 \times 5}$

•°• We got the simple interest as Rs.126

Now, finding out amount,

•°• Required amount = P + S.I = Rs. 7000 + Rs. 126 = Rs. 7126
