Given:

Kalpana's marks = 650

Sudha's marks = 546

Kalpana scored 50% marks

Formula used:

Total marks = Kalpana's marks / Kalpana's percentage = 650 / 50% = 650 / 0.5 = 1300

Calculation:

Sudha's percentage = (Sudha's marks / Total marks) × 100

⇒ Sudha's percentage = (546 / 1300) × 100 = 42%

∴ Sudha scored 42% marks
