Step-by-Step Solution
The complete worked solution.
Every step explained — no skipped algebra.
Let the minimum score = x.
∴ Maximum score = x + 100
∴ x + (x + 100) = 30 × 42 – 40 × 28
⇒ 2x + 100 = 1260 – 1120 = 140
⇒ 2x = 140 – 100 = 40
∴ x = 20
Hence, the maximum score = x + 100
= 20 + 100 = 120
Final Answer: Option B — 120
