Penultimate 5761

The boy was practicing shooting at the basket. Out of the first 12 attempts, he missed 9 times. He was successful in all other attempts except a single penultimate throw. He thus achieved exactly half the success rate (he hit the basket in half of the attempts). How many times did the boy shoot the basket?

Correct answer:

n =  20

Step-by-step explanation:


(12-9)+(n-12-1) = 0.5 · n

0.5n = 10


n = 10/0.5 = 20

n = 20
