ATSA Variables and Equations Memory 4 — Questions and Answers
Question 1: You see: K=3, L=K×K, M=L+K. What is M?
Correct answer: 12
L = 3 × 3 = 9, then M = 9 + 3 = 12.
Question 2: A display shows A=16, B=A÷4, C=A-B. What is C?
Correct answer: 12
B = 16 ÷ 4 = 4, then C = 16 - 4 = 12.
Question 3: Given S=5, T=S+5, U=T×S. What is U-S?
- 40
- 45 (Correct answer)
- 50
- 55
Correct answer: 45
T = 10, U = 10 × 5 = 50, U - S = 50 - 5 = 45.
Question 4: Memorize: R=8, Q=R÷2, P=Q+R+Q. What is P?
- 14
- 16 (Correct answer)
- 18
- 20
Correct answer: 16
Q = 8 ÷ 2 = 4, then P = 4 + 8 + 4 = 16.
Question 5: Given E=7, F=E+1, G=F×E. What is G-E?
- 43
- 47
- 49 (Correct answer)
- 56
Correct answer: 49
F = 8, G = 8 × 7 = 56, G - E = 56 - 7 = 49.
Question 6: You are given: X=20, Y=X÷4, Z=Y×Y. What is Z+Y?
- 25
- 27
- 30 (Correct answer)
- 35
Correct answer: 30
Y = 20 ÷ 4 = 5, Z = 5 × 5 = 25, Z + Y = 25 + 5 = 30.
Question 7: Variables shown: A=3, B=A+A, C=B×A, D=C-B. What is D?
Correct answer: 12
B = 6, C = 6 × 3 = 18, D = 18 - 6 = 12.
