Answer 2

The principle amount x=Rs 250

Step-by-step explanation:

Rate of interest,r=12%

Time,t=5 years

Amount=Rs 400

Let P be the principle amount

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

Where P=Principle value

r=Rate of interest(in %)

t=Time in years

Substitute the values then we get

S.I=$\frac{x\times 12\times 5}{100}=\frac{3x}{5}$

Amount=Principle value+S.I

Substitute the  values then we get

$400=x+\frac{3x}{5}$

$400=\frac{5x+3x}{5}$

$400=\frac{8x}{5}$

$400\times 5=8x$

$x=\frac{400\times 5}{8}=250$

Hence, the principle amount x=Rs 250
