Question

P=1200 RS, R=12%, N=3 years, I=?,A=?​

Answer 1

$\sf \Large Solution!!$

$\sf \large Given:$

$\sf \to Principle(P)=Rs\:1200$

$\sf \to Rate\:of\:interest(R)=12\%$

$\sf \to Time(N)=3\:years$

$\sf \large To\:find:$

$\sf \to Interest(I)$

$\sf \to Amount(A)$

$\sf$

$\sf \to I=\dfrac{P\times R\times N}{100}$

$\sf \to I=\dfrac{12\cancel{00}\times 12\times 3}{1\cancel{00}}$

$\sf \to Interest=Rs\:432$

$\sf \to Amount=Principle+Interest$

$\sf \to Amount=Rs\:1200+Rs\:432$

$\sf \to Amount=Rs\:1632$
