Average of Kanchan's marks in 7 subjects = 75
Average in six subjects excluding Science = 72
Formula used:
Total marks in 7 subjects = Average × Number of subjects
Total marks in 6 subjects excluding Science = Average × Number of subjects
Calculation:
Total marks in 7 subjects = 75 × 7
⇒ 525
Total marks in 6 subjects excluding Science = 72 × 6

Marks in Science = Total marks in 7 subjects - Total marks in 6 subjects
⇒ 525 - 432
⇒ 93
∴ The correct answer is option 1.
