Show Answer

Answer:

Correct Answer: D

Solution:

(d) Let B’s capital be Rs. x. Ratio of profits of A and B $ =[(32000\times 4)+(43000\times 8):[(x\times 8)+(x-2000)\times 4] $ As the profit received by A and B are equal.

$ \therefore $ $ (32000\times 4)+(43000\times 8)=(x\times 8)+(x-2000)\times 4 $

$ \Rightarrow $ $ 8x+4x-8000=128000+344000 $

$ \Rightarrow $ $ 12x=472000+8000 $

$ \Rightarrow $ $ 12x=480000 $

$ \Rightarrow $ $ x=Rs\text{. 40000} $
