Kalpana and Sudha got 656 and 697 marks, respectively, in the same examination. If Kalpana scored 32% marks, then what is the percentage of marks scored by Sudha?​

Correct option is C

Given:

Kalpana's marks = 656

Sudha's marks = 697

Kalpana's percentage = 32%

Concept Used:

$$\text{Total marks} = \frac{\text{Kalpana's marks}}{\text{Kalpana's percentage}} \times 100\\ \ \\\text{Sudha's percentage} = \frac{\text{Sudha's marks}}{\text{Total marks}} \times 100$$​

Solution:

Total marks = $$\frac{656}{32} \times 100 = 2050$$​

Sudha’s percentage = $$\frac{697}{2050} \times 100 = 34\%$$
