Answer:
Interest is $420090 .
Step-by-step explanation:
Formula
[tex]Simple\ interest = \frac{Principle\times Rate\times Time}{100}[/tex]
As given
P = $1400,300
t = 4
[tex]r = 7 \frac{1}{2}\%[/tex]
[tex]r = \frac{15}{2}\%[/tex]
r = 7.5 %
Putting all the values in the formula
[tex]Simple\ interest = \frac{1400300\times 7.5\times 4}{100}[/tex]
[tex]Simple\ interest = \frac{4200900}{100}[/tex]
Simple interest = $ 420090
Therefore the interest is $420090 .
