Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 60
Let 1st student got X marks, Hence the marks of 2nd student will be X + 20
A/c to question,
60% of (X + X + 20) = (X + 20)
6(2X + 20)/10= (X + 20)
12X + 120 = 10X + 200
2X = 80 , X = 40
Marks of student who got more marks is X + 20 = 60
