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:
Answer: Option
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.

Instead of calculating using variables, use options to find the answer.
42 is 56% of 75, hence 3 is the answer.

Percentage diff is 12%.
So 12% is equal to 9 marks.
So for 56% whats the marks(x).
We get x = 56*9/12.
= 42.

We get x = 56*9/12.
= 42.

25(x+9) = 14(2x+9),
25x + 234 = 28x + 126,
25x - 28x = 126 - 234,
3x = 108,
x = 108/3,
x = 33,
y = 33 + 9 = 42.
25x + 234 = 28x + 126,
25x - 28x = 126 - 234,
3x = 108,
x = 108/3,
x = 33,
y = 33 + 9 = 42.

Can't we assume the mark's of another person :-X & those who have less:-X-9?
Likewise;
(X+X-9)*56/100 = X.
Likewise;
(X+X-9)*56/100 = X.

Total 100%.
One got 56 then the other got 44.
Diff 12%=9 (one got 9 marks more),
56%=42.
And 44%=33.

@Anthea. You do by simply dividing 56/100 by least divisible 2 then you got answer 14/25. Hope it's clear !

First, sum all the option and find its 56%.
in option 42+33=75.
75 of 56% =42.
42-9=33.
in option 42+33=75.
75 of 56% =42.
42-9=33.

Answer is C.
I have directly used option to get the answer.
So, 42/75*100 =56%; (42+33 =75).
