Correct Answer: B
Solution :
| 60% of 540 + 45% of Rs. = 468 |
| \[\Rightarrow \] \[\frac{60}{100}\times 540+\frac{45}{100}\times ?=468\] |
| \[\Rightarrow \] \[\frac{45}{100}\times ?+6\times 54=468\] |
| \[\Rightarrow \] \[\frac{45}{100}\times ?+324=468\] |
| \[\Rightarrow \] \[\frac{45}{100}\times ?=468-324\] |
| \[\Rightarrow \] \[\frac{45}{100}\times ?=144\]\[\Rightarrow \]\[?=\frac{144\times 100}{45}\] |
| \[?=320\] |
