Answer:

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 $
