Quantitative — Algebra (الجبر) for the GAT (KSA) Exam

Algebra is the core of the GAT Quantitative section, covering: linear equations, systems of equations, quadratic equations, inequalities, and functions. Algebraic reasoning questions test the ability to translate word problems into equations and solve them efficiently.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

!Solving quadratic equations without checking whether factoring or the quadratic formula is faster
!Inequality errors: forgetting to flip the inequality sign when multiplying/dividing by a negative number
!Function notation errors: confusing f(x) with x × f

Study tips

1Master the three methods for solving quadratics: factoring, completing the square, and the quadratic formula.
2Memorize the inequality rule: multiplying or dividing both sides by a negative number reverses the inequality direction.
3Practice translating Arabic word problems into algebraic expressions — this is the key skill for word-problem algebra.

Sample GAT (KSA) Quantitative — Algebra (الجبر) questions

These sample items mirror the format and difficulty of real GAT (KSA) questions. Practice with thousands more on the free Koydo question bank.

1
Solve: 2x + 5 = 17
- Ax = 4
- Bx = 6Correct
- Cx = 11
- Dx = 5
Why this answer?
2x + 5 = 17 → 2x = 17 − 5 = 12 → x = 6. This tests basic linear equation solving — subtract the constant, then divide by the coefficient.
2
If f(x) = 2x² − 3, what is f(3)?
- A9
- B15Correct
- C21
- D3
Why this answer?
f(3) = 2(3)² − 3 = 2(9) − 3 = 18 − 3 = 15. Substitute x = 3 into the function expression.
