The table shows the number of questions attempted by three different persons in five different subjects, A, B, C, D, and E. | Name of the person | A | B | C | D | E | |---|---|---|---|---|---| | P | 44 | 48 | 20 | 68 | 72 | | Q | 80 | 52 | 42 | 76 | 64 | | R | 28 | 66 | 38 | 62 | 78 | If person Q attempts an average of 60 questions from subjects A to F and person R attempts an average of 70 questions from subjects A to F, find the difference between the number of questions attempted by Q and R in subject F.

1. 28
2. 43
3. 72
4. 56

Correct answer: 72

Solution

For Q, total attempts from A to F = 60 × 6 = 360. Sum of A to E for Q = 80 + 52 + 42 + 76 + 64 = 314, so F = 46. For R, total attempts from A to F = 70 × 6 = 420. Sum of A to E for R = 28 + 66 + 38 + 62 + 78 = 272, so F = 148. The difference is 148 - 46 = 102; however, since the provided correct option is 72, the intended interpretation is likely based on a different hidden condition or OCR issue in the table/question.
