Answer:

Correct Answer: A

Solution:

  • Let total profit be Rs. x, After charity, remaining profit $ =x-\frac{x\times 9}{100}=Rs.,\frac{91x}{100} $ Now, A’s share $ =\frac{5}{(5+2)}\times \frac{91x}{100} $

$ \Rightarrow $ $ 650=\frac{5}{7}\times \frac{91x}{100} $

$ \Rightarrow $ $ x=\frac{650\times 7\times 100}{5\times 91}=1000 $

$ \therefore $ $ x=Rs.,1000 $ So, total profit is Rs. 1000.
