Sorry, the pic isn't very clear. Is the first score 50?

Which question

If the average of the 3 scores is 130, then we know that the total score is 130x3=390. Subtract the first score from 390 forms the total for score 2 and 3.

390-50 = 340 For third score to be smallest possible, second score need to be largest possible. Since it starts with 1 hundred, the largest possible is 199. So 340 - 199 = 141. So the third score is 141.
