A) Rs. 300
B) Rs. 350
C) Rs. 600
D) Rs. 425
Correct Answer: C
Solution :
[c] Let principal = Rs. P \[\therefore \] \[SI=\text{Rs}.(P-312),\] \[r=6%\]and \[t=8\,\,yr\] \[\Rightarrow \] \[SI=\frac{P\times r\times t}{100}\] \[\Rightarrow \] \[P-312=\frac{P\times 6\times 8}{100}\] \[\Rightarrow \] \[100P-31200=48P\] \[\Rightarrow \] \[52\,P=31200\]\[\Rightarrow \]\[P=\text{Rs}.\,\,600\] |
