$\large\underline{\underline{\sf{\maltese\:\: \red{Given \: : }}}}$

• Principal (P) = Rs 56000

• Interest (I) = Rs 280

• Time (T) = 2 years

• Rate (R) = ?

$\large\underline{\underline{\sf{\maltese\:\: \red{Concept \: Used \: : }}}}$

$\bold{R = \dfrac {SI \: \times \: 100}{P \:\times\: T}}$

$\large\underline{\underline{\sf{\maltese\:\: \red{Solution \: :}}}}$

$\sf R = \dfrac {SI \: \times \: 100}{P \:\times\: T}$

$\sf R = \dfrac {Rs \: 280 \: \times \: 100 }{Rs \: 56000 \: \times \: 2}$

$\sf R = \dfrac {1}{4}$

$\sf R = 0.25\%$

$\sf Rate = 0.25 \: \%\: p.a. \:(per \: annum)$
