Let their marks be (x + 9) and x.
Then, x + 9 = 56/100(x + 9 + x)
⇒ 25(x + 9) = 14(2x + 9)
⇒ 3x = 99
⇒ x = 33
So, their marks are 42 and 33.
Then, x + 9 = 56/100(x + 9 + x)
⇒ 25(x + 9) = 14(2x + 9)
⇒ 3x = 99
⇒ x = 33
So, their marks are 42 and 33.

Let's assume the marks obtained by the two students are x and y, where x is the higher score.
According to the given information:
1. One student secured 9 marks more than the other: x = y + 9
2. The higher score is 56% of the sum of their marks: x = 0.56(x + y)
To solve this problem, we can use the given equations to find the values of x and y.
Equation 1: x = y + 9
Equation 2: x = 0.56(x + y)
Now, let's substitute the value of x from Equation 1 into Equation 2:
y + 9 = 0.56(y + 9 + y)
Simplifying the equation:
y + 9 = 0.56(2y + 9)
y + 9 = 1.12y + 5.04
y - 1.12y = 5.04 - 9
-0.12y = -3.96
y = -3.96 / -0.12
y = 33
Now, substitute the value of y back into Equation 1 to find the value of x:
x = y + 9
x = 33 + 9
x = 42
Therefore, the marks obtained by the two students are 42 and 33, which is represented by option C.

Simplifying the equation:
y + 9 = 0.56(2y + 9)
y + 9 = 1.12y + 5.04
y - 1.12y = 5.04 - 9
-0.12y = -3.96
y = -3.96 / -0.12
y = 33
Now, substitute the value of y back into Equation 1 to find the value of x:
x = y + 9
x = 33 + 9
x = 42
Therefore, the marks obtained by the two students are 42 and 33, which is represented by option C.
