Answer:

Correct Answer: B

Solution:

  • Let Rubina s monthly salary be Rs. $ x. $ Then, 75% of 16% of $ x=6567 $

$ \Rightarrow $ $ \frac{75}{100}\times \frac{16}{100}\times x=6567 $

$ \Rightarrow $ $ \frac{3}{4}\times \frac{16}{100}\times x=6567 $

$ \Rightarrow $ $ x=\frac{6567\times 100}{12}=25\times 2189 $ $ =Rs.54725 $
