A) Rs. 120
B) Rs. 140
C) Rs. 160
D) Rs. 180
Correct Answer: C
Solution :
Let first part be Rs. x, then second part is \[Rs.(640-x)\] By given condition, \[\frac{x\times 3\times 6}{100}=\frac{(640-x)\times 6\times 9}{100}\] \[\Rightarrow \] \[4x=640\times 3\] \[\Rightarrow \] \[x=Rs.\,480\] \[\therefore \] Required second part \[=Rs.(640-480)\] \[=Rs.160\]You need to login to perform this action.
