Question

The marks obtained by ravi in history science and mathematics e93 out of 100,78 out of 150 and 177 out of 200 respectively find his average score in percent

Answer 1

Percentage average score =
{(93+78+177)/(100+150+200)} × 100
= (348/450) × 100
= 0.773×100 = 77.3%

Answer 2

Answer:

Average score in percent = 77.33%

Step-by-step explanation:

Marks obtained in History = 93 out of 100

Marks obtained in Science = 78 out of 150

Marks obtained in Mathematics = 177 out of 200

To find the average score in percent : we first need to find the average score of marks obtained by Ravi and then multiply the average score by 100 to get the required average percentage :

Total marks obtained = 93 + 78 + 177 = 348

Maximum marks = 100 + 150 + 200 = 450

$\text{Average Marks = }\frac{348}{450}\approx 0.7733\\\\\bf\implies\textbf{Percentage = }0.7733\times 100 = 77.33\%$
