Marks scored by five students A, B, C, D, and E in three subjects (Maths, English and Physics). Total marks for each subject are 100.

What is the percentage marks obtained by E in all three subjects together? (Assuming maximum marks for each subject are 100.)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 60
Marks of E in Maths = 60
Marks of E in English = 50
Marks of E in Physics = 70
Total marks of E = 60 + 50 + 70 = 180
Percentage marks of E = (180/300) × 100
= 60%
