Show Answer

Answer:

Correct Answer: B

Solution:

  • Let investment of $ A=x, $ Investment of $ B=2x $ and investment of $ C=3x $

$ \therefore $ As share: B’s share: C’s share $ =(x\times 12):(2x\times 6):(3x\times 4) $ $ =12x:12x:12x $ $ =1:1:1 $

$ \therefore $ C’s share $ =\frac{1}{1+1+1}\times 54000 $ $ =\frac{1}{3}\times 54000=Rs\text{. 18000} $
