Question 1
The save rate of a goalkeeper is the percentage given by the number of shots on his target that he has saved divided by the total number of shots on his target. At a given time during a football match, a certain goalkeeper’s save rate was 75%. After failing to save the next three shots on his target, his save rate went down to 60%. What is the minimum number of shots on target that he needs to save in order to raise his save rate back to at least 75%?
