WAEC Mathematics (Obj & Essay) Questions and Answers Structure
The WAEC Mathematics exam consists of two main sections:
Objective (Obj) Section
-
- This section contains multiple-choice questions (MCQs) that test your basic understanding of core mathematical concepts.
- You will be required to choose the correct answer from a list of options.
Essay Section
-
-
- The essay section requires you to write detailed solutions to mathematical problems.
- These questions typically involve algebra, calculus, geometry, trigonometry, and other areas of mathematics.
- You will need to show all the steps in your calculations to earn full marks.

WAEC Mathematics Objective (Obj) Questions
The objective section will test your understanding of foundational concepts and your ability to recognize correct answers quickly. Below are some examples of possible objective questions that may appear on the 2026/2027 WAEC Mathematics exam:
1. Algebra
- Question: What is the value of ( x ) in the equation ( 3x + 7 = 22 )?
a) 3
b) 5
c) 7
d) 10
Answer: b) 5
Explanation: To solve for ( x ), subtract 7 from both sides of the equation:
( 3x = 22 – 7 )
( 3x = 15 )
Now divide both sides by 3:
( x = 15 / 3 = 5 ).
2. Geometry
- Question: The perimeter of a rectangle is 30 cm. If the length is 8 cm, what is the width?
a) 4 cm
b) 5 cm
c) 6 cm
d) 7 cm
Answer: b) 5 cm
Explanation: The formula for the perimeter of a rectangle is ( P = 2L + 2W ), where ( L ) is the length and ( W ) is the width.
Substitute the known values:
( 30 = 2(8) + 2W )
( 30 = 16 + 2W )
Now, subtract 16 from both sides:
( 2W = 14 )
Finally, divide by 2:
( W = 7 , \text{cm} ).
3. Trigonometry
- Question: If ( \sin \theta = 0.6 ), what is the value of ( \cos \theta ) if ( \theta ) is an acute angle?
a) 0.4
b) 0.8
c) 1.0
d) 0.6
Answer: a) 0.4
Explanation: Using the identity ( \sin^2 \theta + \cos^2 \theta = 1 ), we can solve for ( \cos \theta ):
( 0.6^2 + \cos^2 \theta = 1 )
( 0.36 + \cos^2 \theta = 1 )
Subtract 0.36 from both sides:
( \cos^2 \theta = 0.64 )
Taking the square root of both sides gives:
( \cos \theta = 0.8 ).
4. Probability
- Question: A bag contains 4 red balls, 3 green balls, and 5 blue balls. What is the probability of randomly selecting a green ball from the bag?
a) ( \frac{3}{12} )
b) ( \frac{5}{12} )
c) ( \frac{1}{4} )
d) ( \frac{3}{10} )
Answer: a) ( \frac{3}{12} )
Explanation: The total number of balls is ( 4 + 3 + 5 = 12 ). The number of green balls is 3, so the probability of selecting a green ball is:
( \frac{3}{12} = \frac{1}{4} ).
5. Sets and Venn Diagrams
- Question: If set ( A = {1, 2, 3, 4} ) and set ( B = {3, 4, 5, 6} ), what is the intersection of sets ( A ) and ( B )?
a) ( {1, 2} )
b) ( {3, 4} )
c) ( {5, 6} )
d) ( {3, 4, 5, 6} )
Answer: b) ( {3, 4} )
Explanation: The intersection of two sets consists of the elements that are common to both sets. The common elements in ( A ) and ( B ) are 3 and 4.
