On three tests, each graded on a scale of 0 to 100, Jim had an average score of 78. If Jim pulls his average up to 84 after taking two additional tests, what is the lowest possible score he could have received on one of the last two tests?
----------
To average 84 in five tests Jim would need 5*84 = 420 points.
-----------------
After three tests Jim has 3*78 = 234 points.
He needs 186 points in the remaining tests.
If one of the tests is 100 the other could be 86
