A) Rs. 650
B) Rs. 550
C) Rs. 1250
D) Rs. 750
Correct Answer: D
Solution :
Let sum lent at 8% = Rs. x \[\therefore \]Sum lent at 5% = Rs.\[(1550-x)\] Given,\[\frac{x\times 3\times 8}{100}+\frac{(1550-x)\times 3\times 5}{100}=300\] \[\Rightarrow \] \[\frac{8x}{100}+\frac{(1550-x)\times 5}{100}=100\] \[\Rightarrow \] \[8x-5x+7750=10000\] \[\Rightarrow \] \[3x=10000-7750=2250\] \[\therefore \]\[x=\frac{2250}{3}=750\]You need to login to perform this action.
