Solution:

Ambika got 99 percent marks in Mathematics, 76 percent marks in Hindi, 61 percent in English, 84 percent in Science and 95% in Social Science.

Each subject carries 100 marks.

We have to find the percentage of marks obtained by Ambika in the aggregate of all the subjects.

Marks obtained in Mathematics = 99% of 100

= (99/100) × 100

= 99

Marks obtained in Hindi = 76% of 100 = 76

Marks obtained in English = 61% of 100 = 61

Marks obtained in Science = 84% of 100 = 84

Marks obtained in Social Science = 95% of 100 = 95

Total marks obtained by Ambika = 99 + 76 + 61 + 84 + 95

= 415

Total marks = 5(100) = 500

Percentage of marks obtained by Ambika = 415/500 × 100

= 415/5

= 83%

Therefore, the required percentage is 83%
