Answer:

Correct Answer: A

Solution:

  • Let the total capital be Rs. x and Babloo’s money is used for y months. Capital of Aayush $ =\frac{x}{4} $

$ \therefore $ Capital of Babloo $ =( x-\frac{x}{4} )=\frac{3x}{4} $ Ratio of investments of Aayush and Babloo $ =( \frac{x}{4}\times 15 ):( \frac{3x}{4}\times y )=\frac{15}{4}:\frac{3y}{4}=5:y $ Ratio of profits of Aayush and Babloo $ =\frac{1}{3}:\frac{2}{3}=1:2 $

$ \therefore $ $ \frac{5}{y}=\frac{1}{2} $
$ \Rightarrow $ $ y=10 $ Hence, Babloo’s money was used for 10 months.
