Question

The Simple Interest on rupees 10000 for 3 years at the rate of 3% per annum is rupees ____

step by step

Answer 1

Given :

• Principal (P) = Rs. 10000
• Rate of interest (r) = 3 years
• Time period (n) = 3%

To Find :

• Simple Interest = ?

Solution :

☯ $\underline{\boldsymbol{According\: to \:the\: Question\:now :}}$

$:\implies\sf Simple \: interest = \dfrac{Principal \times Rate \times Time}{100}$

$:\implies\sf Simple \: interest = \dfrac{10000 \times 3\times 3}{100}$

$:\implies\sf Simple \: interest = \dfrac{90000 }{100}$

$:\implies \underline{ \boxed{\sf Simple \: interest =Rs. \: 900 }}$

$\therefore\:\underline{\textsf{The Simple Interest is \textbf{Rs. 900}}}.$

$\boxed{\underline{\underline{\bigstar\:\bf\:Extra\: knowledge\:\bigstar}}}$

$\tt 1) Profit = SP - CP$

$\tt 2) Loss = CP - SP$

$\tt 3) Profit\% = (Profit \:in \:Rs.)*100/CP$

$\tt 4) Loss\% = (Loss \:in \:Rs.)*100/CP$

$\tt 5) SP = CP*(100+P\%)/100$

$\tt 6) SP = CP*(100-L\%)/100$

$\tt 7) CP = SP*100/(100+P\%)$

$\tt 8) CP = SP*100/(100-L\%)$

$\tt 9) Discount =MP - SP$

$\tt 10) Discount\%=(Discount \:in \:Rs.)*100/MP$

$\tt 11) MP = SP*100/(100-D\%)$
