Answer:
Correct Answer: B
Solution:
- Let original rate be Rs. x per egg. New rate = 80% of $ x=Rs.\frac{4x}{5} $ Original quantity for $ Rs.,40=\frac{40}{x} $ New quantity $ =40\times \frac{5}{4x}=\frac{50}{x} $
$ \therefore $ $ \frac{50}{x}-\frac{40}{x}=20 $
$ \Rightarrow $ $ \frac{10}{x}=20 $
$ \Rightarrow $ $ x=\frac{10}{20}=\frac{1}{2} $
$ \therefore $ Reduced price = 80% of $ Rs.,\frac{1}{2}=\frac{4}{5}\times \frac{1}{2} $ $ =Rs.\frac{2}{5}=\frac{2}{5}\times 100=40,paise $
