The score for each of the three darts was {10,15,20}

Explanation:

Lowest score was 10

As range was 10, the difference between lowest and highest score is 10 and as lowest score is 10, highest score is 10+10=20.

As the mean of three scores was 15, sum of three scores was

15xx3=45

Now two readings are 10 and 20, hence third reading is

45-10-20=15.

Hence, the score for each of the three darts was {10,15,20}
