Kalpana and Sudha got 621 and 522 marks, respectively, in the same examination. If Kalpana scored 69% marks, then what is the percentage of marks scored by Sudha?​

Correct option is A

Given:

Kalpana's marks = 621

Kalpana's percentage = 69%

Sudha's marks = 522

Solution:

Total Marks = $$\frac{621}{69} \times 100 = 900$$​

Sudha’s Percentage = $$\left( \frac{522}{900} \right) \times 100 = 58\%$$
