Overview of the NECO Exam

The National Examinations Council (NECO) conducts the Senior Secondary Certificate Examination (SSCE) for students across Nigeria. Mathematics is a compulsory subject, meaning you must pass it to qualify for university or polytechnic admission.

The NECO Mathematics paper usually consists of two main parts:

1. Paper I – Objective Questions (60 questions)

   • Covers algebra, geometry, trigonometry, statistics, and basic arithmetic.

   • Duration: 1 hour 30 minutes.

2. Paper II – Theory Questions (10 structured questions)

   • You’re required to answer 5 or 6 questions.

   • Duration: 2 hours.

The combination of both papers tests your calculation accuracy, problem-solving skill, and ability to explain mathematical steps correctly.

NECO Mathematics Questions and Answers 2026 – Theory Questions and Answers

The theory section requires you to show working steps. Each question carries equal marks, so clarity and accuracy are vital. Below are sample NECO 2026 Mathematics theory questions with short explanations.

Question 1:

Solve for x:
$2x+5=11$

Solution:
Subtract 5 from both sides:
$2x=6$
Divide both sides by 2:
$x=3$

Final Answer: x = 3

Question 2:

A trader bought 5 bags of rice at ₦18,000 each and sold them for ₦21,000 each. Find the percentage profit.

Solution:
Cost Price (CP) = ₦18,000 × 5 = ₦90,000
Selling Price (SP) = ₦21,000 × 5 = ₦105,000
Profit = ₦105,000 – ₦90,000 = ₦15,000
Percentage Profit = 15,00090,000×100=16.7%\frac{15,000}{90,000} × 100 = 16.7\%90,00015,000​×100=16.7%

Final Answer: 16.7%

Question 3:

Find the area of a triangle with base 8 cm and height 6 cm.

Solution:
Area = ½ × base × height
= ½ × 8 × 6 = 24 cm²

Final Answer: 24 cm²

Question 4:

The mean of five numbers is 12. If four of them are 10, 11, 14, and 9, find the fifth number.

Solution:
Let the fifth number be x.
Mean = (10 + 11 + 14 + 9 + x) ÷ 5 = 12
(44 + x) = 60 → x = 16

Final Answer: 16

Question 5:

Find the simple interest on ₦5,000 for 2 years at 8% per annum.

Solution:
SI = (P × R × T) ÷ 100
= (5,000 × 8 × 2) ÷ 100 = ₦800

Final Answer: ₦800

Key Topics and Areas to Study

The NECO 2026 exam covers many math topics, but some areas are always repeated. Focus more on these:

Pro Tip: Study at least five years of NECO past questions. The format doesn’t change much, and certain types of problems appear repeatedly.

Common Mistakes Students Make

Here are the mistakes that cause students to lose easy marks in the NECO Mathematics exam:

1. Skipping working steps: Examiners give marks for correct methods, even if the final answer is wrong. Always show your steps.

2. Poor time management: Don’t spend too long on one question. If it’s difficult, move on and return later.

3. Wrong formula use: Revise all major formulas before the exam.

4. Not using units: Always include units like cm, m², ₦, or %.

5. Careless calculation errors: Use rough work neatly to avoid confusion.

Example Tip:
When solving for the area of a circle, always write πr2\pi r^2πr2 first before substituting values. That alone earns you method marks.
