Every question is an original Abrari practice item. Answers and explanations are inside each item.

Q1 · Linear equations

Solve for x: 3x − 7 = 11

  1. A. x = 4/3
  2. B. x = 6
  3. C. x = 18
  4. D. x = −6
Answer and explanation

Answer: B

Add 7 to both sides: 3x = 18. Divide by 3: x = 6.

Q2 · Exponents

Simplify 2³ × 2²

  1. A. 2⁵
  2. B. 2⁶
  3. C. 4⁵
  4. D. 2¹
Answer and explanation

Answer: A

When multiplying powers with the same base, add the exponents: 2³ × 2² = 2⁵ = 32.

Q3 · Pythagoras

A right-angled triangle has legs of 6 cm and 8 cm. How long is the hypotenuse?

  1. A. 10 cm
  2. B. 14 cm
  3. C. 12 cm
  4. D. 48 cm
Answer and explanation

Answer: A

c² = 6² + 8² = 36 + 64 = 100, so c = 10 cm.

Q4 · Simple interest

What is the simple interest on 2,000 birr at 5% per year for 3 years?

  1. A. 100 birr
  2. B. 300 birr
  3. C. 3,000 birr
  4. D. 150 birr
Answer and explanation

Answer: B

I = P × R × T = 2,000 × 0.05 × 3 = 300 birr.

Q5 · Statistics

What is the mean of 4, 7, 9, 12 and 8?

  1. A. 7
  2. B. 8
  3. C. 9
  4. D. 10
Answer and explanation

Answer: B

Sum = 4 + 7 + 9 + 12 + 8 = 40. There are 5 numbers, so the mean is 40 ÷ 5 = 8.

Q6 · Circles

What is the circumference of a circle with radius 7 cm? (Use π ≈ 22/7.)

  1. A. 22 cm
  2. B. 44 cm
  3. C. 154 cm
  4. D. 49 cm
Answer and explanation

Answer: B

C = 2πr = 2 × 22/7 × 7 = 44 cm. (154 cm² would be the area.)

Q7 · Algebra

Expand (x + 3)(x − 3).

  1. A. x² − 9
  2. B. x² + 9
  3. C. x² − 6x − 9
  4. D. x² + 6
Answer and explanation

Answer: A

This is a difference of two squares: (x + 3)(x − 3) = x² − 3² = x² − 9.

Q8 · Square roots

What is √144 + √25?

  1. A. 13
  2. B. 17
  3. C. 169
  4. D. 19
Answer and explanation

Answer: B

√144 = 12 and √25 = 5, so the sum is 17.
