Answer:

Correct Answer: A

Solution:

  • Let the amount in equity funds in the original amount be Rs. 5x. $ \because $ Profit at the end of first year $ =9x+\frac{30}{100}=Rs\text{. 2}\text{.7}x $ Amount $ =9x+2.7x=11.7x $ $ \because $ Equity fund at the end of first year $ =\frac{7\times 11.7x}{13} $ According to the question, $ \frac{7\times 11.7x}{13}=94500 $

$ \Rightarrow $ $ x=Rs\text{. 15000} $

$ \therefore $ Amount invested in equity funds $ =5x=5\times 15000=Rs\text{.}75000 $
