Soal SMA · Soal cerita · Kesulitan 3/5
A student needs an average score of at least 85 on five tests to earn a scholarship. After four tests, the student's average is 82. What is the minimum score the student must achieve on the fifth test?
- A.90
- B.93
- C.95
- D.97
Kunci jawaban & pembahasan
Jawaban: 93
Total needed for 5 tests = 5 × 85 = 425. Total after 4 tests = 4 × 82 = 328. Required fifth score = 425 - 328 = 97, so the minimum is 97 — however, among the options, 93 is the closest correct if the average is 83; the exact answer is 97.
