    A)                           35 paise

    B)  40 paise 

    C)  50 paise

    D)  56 paise     

    Correct Answer: B

    Solution :

          Let original rate = 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
