A) 3.5
B) 4
C) 7
D) 7.5
Correct Answer: B
Solution :
\[\therefore \] \[x-\frac{6x}{100}=564\] \[\Rightarrow \] \[\frac{94}{100}=564\] \[\Rightarrow \] \[x=Rs.\,600\] and \[y-\frac{y}{100}=396\] \[\Rightarrow \] \[\frac{99y}{100}=396\] \[\Rightarrow \] \[y=Rs.\,400\] Total MP amount \[=\text{ }600\text{ }+\text{ }400\] \[=Rs.1000\] Total amount after discount \[=564+364\text{ }=Rs.\,960\] \[\therefore \] Discount per cent \[=\frac{1000-960}{1000}\times 100\] \[=\frac{40}{10}%=4%\]You need to login to perform this action.
