A) Rs. 15000
B) Rs. 10000
C) Rs. 9000
D) Data inadequate
Correct Answer: B
Solution :
Amount deposited at 18% per annum = Rs. x\[\therefore \] A mount deposited at 15% per annum = Rs. \[(25000-x)\] |
Interest in one year |
\[=\frac{x\times 18\times 1}{100}+\frac{25000-x\times 15\times 1}{100}\] |
\[=\frac{18x}{100}+\frac{375000+15x}{100}=\frac{3x}{100}=3750\] |
According to question, |
\[\frac{3x}{100}+3750=4050\Rightarrow \frac{3x}{100}=300\] |
\[\therefore \] \[x=10000\] |
