A.42, 33
B.42, 36
C.44, 33
D.44, 36
Answer & Explanation
Answer: Option A
Let the marks secured by them be x and (x + 9)
Then sum of their marks = x + (x + 9) = 2x + 9
Given that (x + 9) was 56% of the sum of their marks
=>(x + 9) = 56/100(2x + 9)
=> (x + 9) = 14/25 (2x+9)
=> 25x + 225 = 28x + 126
=> 3x = 99 => x = 33
Then (x + 9) = 33 + 9 = 42
Hence their marks are 33 and 42
