A candidate scoring 25% in an examination fails by 30 marks , while another candidate scores 50 % mark, gets 20 marks more than the minimum pass marks . Find the minimum pass marks. Find the minimum pass percentage.	Choose one:
A) 26	B) 40	C) 88	D) 27	E) 26
Let x be the maximum marks,   Then (25% of x)+30 = (50% of x)-20   \inline \Rightarrow \inline \frac{x}{4}+30 = \frac{x}{2}-20   \inline \Rightarrow 2x-x=120+80=

<output>200</output>
200   Hence maximum marks= 200   Minimum pass marks = \inline \frac{200}{4}+30=80   Hence, minimum pass marks = \inline \frac{80}{200}\times 100=40%   Answer: 40
