DAY 406

Ten students take a test with a maximum score of 100. The average of the ten scores is 92. What is the lowest score a student could have received?

Answer:

20 ................. For the average to be 92, the ten students must have scored a total of 920 points (920/10 = 92). This is 80 points short of the 1,000 possible points.   1000 - 80 = 20.
