Two students appeared for an examination. One of them secured 22
marks more than the other and his marks were 55% of the sum of
their marks
Let the students be A and B
Let the marks secured by B = x
Marks secured by A = x + 22
Sum of their marks of A & B = x + x + 22 = 2x + 22
Accoring to question,
Marks of A = 55% of the sum of marks
⇒ x + 22 = 0.55 × (2x + 22)
⇒ x + 22 = 1.1x + 12.1
⇒ 0.1x = 9.9
⇒ x = 9.9/0.1 = 99 marks
Marks secured by A = 99 + 22 = 121 marks
Therefore the correct answer is 121.

Two students appeared for an examination. One of them secured 22 marks...
Given:
- Two students appeared for an examination.
- One student secured 22 marks more than the other.
Let's assume the marks secured by the first student as x.
Then, the marks secured by the second student would be x + 22.
It is given that the marks of the first student are 55% of the sum of their marks.
So, we can write the equation as:
x = 0.55(x + (x + 22))
Simplifying the equation:
x = 0.55(2x + 22)
x = 1.1x + 12.1
x - 1.1x = 12.1
-0.1x = 12.1
x = -12.1 / -0.1
x = 121
Therefore, the marks secured by the first student are 121.
And the marks secured by the second student are x + 22 = 121 + 22 = 143.
Hence, the correct answer is option 'A' which states that the marks obtained by the students are 121 and 143.

Simplifying the equation:

x = 1.1x + 12.1
x - 1.1x = 12.1
-0.1x = 12.1
x = -12.1 / -0.1
x = 121
Therefore, the marks secured by the first student are 121.
And the marks secured by the second student are x + 22 = 121 + 22 = 143.
Hence, the correct answer is option 'A' which states that the marks obtained by the students are 121 and 143.
