SCAT Quantitative 3 — Questions and Answers
Question 1: Column A: The number of prime numbers between 10 and 20. Column B: 4. Which is greater?
- Column A is greater
- Column B is greater
- They are equal (Correct answer)
- Cannot be determined
Correct answer: They are equal
Primes between 10 and 20: 11, 13, 17, 19 — that is 4 primes, so both columns equal 4.
Question 2: Sarah has $45.00 and spends 1/3 of it on lunch and 2/5 of the remainder on a book. How much does she have left?
- $18.00 (Correct answer)
- $27.00
- $21.00
- $9.00
Correct answer: $18.00
After lunch: $45 − $15 = $30; book: 2/5 × $30 = $12; remaining: $30 − $12 = $18.
Question 3: What is the value of √144 + √25?
- 17 (Correct answer)
- 13
- 169
- 15
Correct answer: 17
√144 = 12 and √25 = 5, so 12 + 5 = 17.
Question 4: Column A: (10 − 4) × 3. Column B: 10 − (4 × 3). Which is greater?
- Column A is greater (Correct answer)
- Column B is greater
- They are equal
- Cannot be determined
Correct answer: Column A is greater
Column A: 6 × 3 = 18; Column B: 10 − 12 = −2; Column A (18) is greater.
Question 5: A class of 30 students scored an average of 82 on a test. What was the total number of points scored?
- 2,460 (Correct answer)
- 2,640
- 246
- 820
Correct answer: 2,460
Total points = average × number of students = 82 × 30 = 2,460.
Question 6: What is 0.04 × 0.5?
- 0.02 (Correct answer)
- 0.002
- 0.2
- 2
Correct answer: 0.02
0.04 × 0.5 = 0.020 = 0.02; multiply the digits and count decimal places.
Question 7: Column A: The area of a square with side 7. Column B: The area of a rectangle with sides 6 and 9. Which is greater?
- Column A is greater
- Column B is greater (Correct answer)
- They are equal
- Cannot be determined
Correct answer: Column B is greater
Column A: 7² = 49; Column B: 6 × 9 = 54; Column B (54) is greater.
