A) Rs. 12000
B) Rs.9000
C) Rs. 6000
D) Rs.8000
Correct Answer: D
Solution :
Simple Interest \[\frac{\text{Principal }\!\!\times\!\!\text{ Rate }\!\!\times\!\!\text{ Time}}{\text{100}}\] Given, \[7840=\frac{P\times 6\times 3}{100}+\frac{P\times 8\times 5}{100}+\frac{P\times 10\times 4}{100}\] or \[7840\times 100=18P=+\,\,40P+40P\] or 98 P = 784000 \[\therefore \] \[P=\frac{784000}{98}=Rs.\,8000\]You need to login to perform this action.
