A) Rs. 8000
B) Rs. 6000
C) Rs. 7000
D) Rs. 7500
Correct Answer: A
Solution :
Let the larger part of the sum = Rs. x \[\therefore \] Smaller part \[Rs.(12000-x)\] According to the question, \[\frac{x\times 3\times 12}{100}=\frac{(1200-x)\times 9\times 16}{2\times 100}\] \[\Rightarrow \] \[36x=(12000-x)72\] \[\Rightarrow \] \[x=(12000-x)\times 2\] \[\Rightarrow \] \[x+2x=24000\] \[\Rightarrow \] \[3x=24000\] \[\Rightarrow \] \[x=\frac{24000}{3}\] \[=Rs.\,8000\]You need to login to perform this action.
