Question 342416: a boy has 5 test scores with an average of 88, what is the lowest score he could receive Found 2 solutions by kcanil08, solver91311:Answer by kcanil08(11) (Show Source):
You can put this solution on YOUR website! when the average is 88 then total score is
5*88 = 440
He should get maximum in 4 tests to calaulate least possible in one test,
100 in 4 tests =400
so his least score is
440-400= 40
in one test.
(PS: I have assumed that full marks in one test is 100.)
To determine the average of numbers, you add up the numbers and divide by . In your case you have an average of 88 for 5 scores, which means that the total of the scores must be .
In order to determine the lowest possible score that he could have obtained on any of his tests, you would have to know the maximum possible score that could have been obtained on any of the exams. (440 minus 4 times the maximum score = the lowest possible score to obtain an 88 average). Since you didn't bother to share that essential piece of information, there is no way to tell what the lowest score could be. I can't even tell if zero is an appropriate lower bound because you didn't share whether or not negative scores are possible.
Present the WHOLE problem and someone here will see what we can do. If what you presented was the whole problem as it was presented to you, go back to your instructor/teacher/professor and ask for the rest of the problem.
