omar has taken 4 exams and his average score so far is a 79.If he gets 100,a perfect score,on the remaining two exams,what will his new average be ?
[(4 * 79) + 200] / 6 = ?
86
To find Omar's new average score, we need to calculate the average of all his exam scores, including the perfect scores he gets on the remaining two exams.
First, let's understand Omar's current situation. He has taken 4 exams, and his average score so far is 79. This means that the sum of his scores is 4 times 79.
Sum of Omar's current scores = 4 exams * average score = 4 * 79
To find Omar's new average score, we also need to consider the perfect scores he gets on the remaining two exams. Each exam has a perfect score of 100.
To calculate Omar's new average, we need to add the scores he gets on the remaining two exams and divide by the total number of exams.
Sum of Omar's new scores = Sum of current scores + perfect score on exam 1 + perfect score on exam 2
= 4 * 79 + 100 + 100
Total number of exams = 4 (previous exams) + 2 (remaining exams) = 6
New average score = Sum of new scores / Total number of exams
Plugging in the values, we get:
New average score = (4 * 79 + 100 + 100) / 6
Now let's calculate it.
New average score = (316 + 100 + 100) / 6
= 616 / 6
= 102.67 (approximately)
Therefore, Omar's new average score, if he gets perfect scores on the remaining two exams, would be approximately 102.67.
