Note that it is given that a number under par represents a negative number, a number over par represents a positive number and a par represent 0.
For the first hole with 1 under par, the score will be -1.
For the second hole with 3 over par, the score will be +3.
For the third hole with 2 under par, the score is -2.
The fourth hole with a par is equivalent to a score of 0.
While the fifth hole with 3 over par, the score will be +3.
To calculate the total score of the golfer at the end of the course, find the sum of the scores from each final 5 holes noting that the golfer was at par (0 score) before the final 5 holes.
The total score is:
It follows that since a positive number means over par, the golfer was over par with 3 strokes at the end of the golf course.
Hence, the correct option is the third option.
