2.	Two students appeared at an examination. One of them secured 9 marks more than the other and his marks was 56% of the sum of their marks. The marks obtained by them are?
	A.	39, 30
	B.	41, 32
	C.	42, 33
	D.	43, 34

Answer: Option C

Explanation:

Let their marks be (x + 9) and x.

Then, x + 9 = 56 (x + 9 + x)

100

25(x + 9) = 14(2x + 9)

3x = 99

x = 33

So, their marks are 42 and 33.
