Show Answer

Answer:

Correct Answer: B

Solution:

  • Ratio of shares of A, B, C, D $ =(24\times 3):(10\times 5):(35\times 4):(21\times 3) $ = 72: 50: 140: 63 Let the total rent be Rs. x Then, As share $ =Rs\text{.}\frac{72x}{325} $

$ \therefore $ $ \frac{72x}{325}=720 $

$ \Rightarrow $ $ x=3250 $
