| Rubina decided to donate 16% of her monthly salary to an NGO. On the day of donation, she changed her mind and donated Rs. 6567 which was 75% of what she had decided earlier. How much is Rubina's monthly salary? |
| [Canara Bank (PO) 2009] |
A) Rs. 8756
B) Rs. 54725
C) Rs. 656700
D) Rs. 45696
E) None of these
Correct Answer: B
Solution :
| Let Rubina s monthly salary be Rs. \[x.\] |
| Then, 75% of 16% of \[x=6567\] |
| \[\Rightarrow \] \[\frac{75}{100}\times \frac{16}{100}\times x=6567\] |
| \[\Rightarrow \] \[\frac{3}{4}\times \frac{16}{100}\times x=6567\] |
| \[\Rightarrow \]\[x=\frac{6567\times 100}{12}=25\times 2189\] |
| \[=\text{Rs}.\,\,54725\] |
