A) Rs. 15000
B) Rs. 12000
C) Rs. 9000
D) Rs. 10000
Correct Answer: D
Solution :
Amount deposited at 18% per annum =Rs. x \[\therefore \]Amount deposited at 15% per annum = Rs. \[(25000-x)\] Interest in one year \[=\frac{x\times 18\times 1}{100}+\frac{(25000-x)\times 15\times 1}{100}\] \[=\frac{18x}{100}+\frac{37500-15x}{100}=\frac{3x}{100}+3750\] According to the question, \[\frac{3x}{100}+3750=4050\] \[\Rightarrow \] \[\frac{3x}{100}=300\therefore x=10000\]You need to login to perform this action.
