Amount deposited in the bank for one year is Rs. 9000 , which is less than 10000.

So the rate of interest given by the bank, r=5 %.

Principal amount, P=9000

Time, t=1 year

Simple interest

[tex] \\ \rm=\frac{P \times r \times t}{100} [/tex]

[tex] \\ \rm =\frac{90 \cancel{00} \times 5 \times 1} {\cancel{100} }[/tex]

[tex] \\ \rm=90 \times 5 \boxed{\color{olive} \rm =R s .450 }[/tex]
