36% of the maximum marks are required to pass a test. A student get 109 marks and is declared invalid by 35 marks .find the maximum marks.
Sol:
Let x be the maximum marks.
Passing Marks = (36*x)/100
ATQ
109 = (36*x)/100 - 35
144 = (36*x)/100
x/100 = 144/36= 4
x = 400
Therefore, maximum marks are 400.
