Show Answer

Answer:

Correct Answer: B

Solution:

  • Ratio of rents of A, B, C and D $ =(18\times 4):(25\times 2):(28\times 5):(21\times 3) $ $ =72:50:140:63 $ Let the total rent be x. Then, As share $ =\frac{72x}{(72+50+140+63)}=\frac{72x}{325} $ According to the question, $ \frac{72x}{325}=720 $
    $ \Rightarrow $ $ x=\frac{720\times 325}{72} $

$ \therefore $ Total rent = Rs. 3250
