Answer:
15 times
Step-by-step explanation:
let x be the times he hit and y be the times he miss
therefore x + y = 50 => y = 50 - x
and, 20x -8y = 20
=> 20x -8(50-x) = 20
=> 20x - 400 +8x = 20
=> 28x = 420
=> x = 15
he hit bulls eye 15 times

Step-by-step explanation:
Let n be the number of times, the boy hits the bulls eye.
20 * n - (50 - n) * 8 = 20
28 * n = 420
Hence, n = 420 / 8 = 15
