Answer 2

The principle amount,P=Rs 400

Step-by-step explanation:

Let principle value ,Px

Rate of interest=r=5%

Time,t=8 years

Amount=Rs 560

S.I=$\frac{P\times r\times t}{100}$

Where P=Principle value

r=Rate of interest (in %)

t=Time (in years)

Using the formula

$S.I=\frac{x\times 5\times 8}{100}=\frac{2x}{5}$

Amount=Principle amount+S.I

Using the formula

$560=x+\frac{2x}{5}$

$560=\frac{5x+2x}{5}=\frac{7x}{5}$

$x=\frac{560\times 5}{7}=400$

Hence,the principle amount,P=Rs 400
