neha scored 75% in science,95% in maths and 70% in english. If the max. marks in these subjects were 80,100and 70,respectively. find her aggregate percentage.

80 * 75 % = 80 * 75 / 100 = 6000 / 100 = 60

100 * 95 % = 100 * 95 / 100 = 9500 / 100 = 95

70 * 70 % = 70 * 70 / 100 = 49

[ ( 60 + 95 + 49 ) / ( 80 + 100 + 70 ) ] * 100 % =

( 204 / 250 ) * 100 % = 0.816 * 100 % = 81.6 %

Nice question..

To calculate Neha's aggregate percentage, we need to find the average of her scores in the three subjects.

Step 1: Convert the percentages to decimal form by dividing them by 100.

Science: 75/100 = 0.75
Maths: 95/100 = 0.95
English: 70/100 = 0.70

Step 2: Multiply each decimal by the maximum marks for the respective subject.

Science: 0.75 * 80 = 60
Maths: 0.95 * 100 = 95
English: 0.70 * 70 = 49

Step 3: Calculate the sum of the marks obtained in all subjects.

Total marks obtained = 60 + 95 + 49 = 204

Step 4: Calculate the aggregate percentage by dividing the total marks obtained by the total maximum marks and multiplying by 100.

Aggregate percentage = (204 / (80 + 100 + 70))*100
Aggregate percentage ≈ 68.73%

Therefore, Neha's aggregate percentage is approximately 68.73%.

To find Neha's aggregate percentage, we need to calculate the average of her individual subject percentages.

Step 1: Calculate the individual subject percentages:
- In science, Neha scored 75% out of a maximum of 80 marks. So, her percentage in science is (75/80) * 100 = 93.75%.
- In maths, Neha scored 95% out of a maximum of 100 marks. So, her percentage in maths is (95/100) * 100 = 95%.
- In English, Neha scored 70% out of a maximum of 70 marks. So, her percentage in English is (70/70) * 100 = 100%.

Step 2: Calculate the average of the individual subject percentages:
To calculate the average, add up the percentages and divide by the number of subjects.
Aggregate percentage = (93.75 + 95 + 100) / 3.

Step 3: Calculate the aggregate percentage:
Aggregate percentage = (289.25) / 3 = 96.42%.

Therefore, Neha's aggregate percentage is approximately 96.42%.
