| Students | ||
| Subjects | A | B |
| P | 180 | 90 |
| Q | 240 | 420 |
| R | 360 | 390 |
| S | 300 | 210 |
| T | 60 | 270 |
| U | 330 | 120 |
What is the difference between the total marks obtained by A and B in all the 6 subjects?
Answer & explanation
Correct answer: option 2
Total marks obtained by A = 180 + 240 + 360 + 300 + 60 + 330 = 1470
Total marks obtained by B = 90 + 420 + 390 + 210 + 270 + 120 = 1500
Difference in marks of A & B = 1500 - 1470 = 30
