Question

Two students appeared at an examination. one of them secured 9 marks more than the other and his marks were 56% of the sum of their marks. what are the marks obtained by them? *

Answer 1

Give the two understudies a chance to be A and B. A secures x Marks thus B secures x+9. B's imprints (x+9) were 56% of the entirety of their marks(x+x+9). 
Henceforth, 
x+9= 0.56(2x+ 9) 
x+9= 1.12x + 5.04 
3.96= 0.12x 
In this way x = 33 
A secures 33 marks 
B secures 42 marks
