Show Answer

Answer:

Correct Answer: A

Solution:

  • Let Shilpa deposited Rs. x in each bank.

$ \therefore $ $ SI=\frac{Principal\times Rate\times Time}{100} $

$ \Rightarrow $ $ \frac{x\times 10\times 3}{100}+\frac{x\times 12\times 3}{100}=3300 $

$ \Rightarrow $ $ 30x+36x=3300\times 100 $

$ \Rightarrow $ $ x=\frac{3300\times 100}{66}=Rs\text{.}5000 $ Thus, total amount deposited $ =Rs\text{.}10000 $
