Here is an explanation of Section I of the JAMB Mathematics syllabus, along with 10 JAMB-style questions for each sub-topic.
Explanation: This topic covers different ways of representing numbers using various bases (radix systems), from base 2 (binary) to base 10 (decimal). Key skills include converting numbers between any two bases, including those with fractional parts, and performing basic arithmetic operations (addition, subtraction, multiplication, division) directly within a given non-decimal base. Modulo arithmetic, which deals with remainders after division, is also included.
Questions:
Convert to base 10. A. 25 B. 27 C. 29 D. 31
Convert to base 3. A. B. C. D.
Convert to base 8. A. B. C. D.
Evaluate . A. B. C. D.
Subtract from . A. B. C. D.
Multiply by . A. B. C. D.
Divide by . A. B. C. D.
If , find . A. 5 B. 6 C. 7 D. 8
Convert to base 2. A. B. C. D.
Evaluate . A. 1 B. 2 C. 3 D. 4
Explanation: This section covers fundamental arithmetic operations with fractions and decimals, along with methods for rounding numbers to a specified number of significant figures or decimal places. It also includes practical applications of percentages such as calculating percentage error, simple interest, profit/loss, and problems involving ratios, proportions, rates, shares, and Value Added Tax (VAT).
Questions:
Simplify . A. B. C. D.
Express to 2 significant figures. A. B. C. D.
Round to 3 decimal places. A. B. C. D.
A student measured the length of a line as . If the actual length is , calculate the percentage error. A. B. C. D.
Calculate the simple interest on for 3 years at per annum. A. B. C. D.
A trader bought an item for and sold it for . Calculate the percentage profit. A. B. C. D.
The ratio of boys to girls in a class is . If there are 24 boys, how many girls are there? A. 30 B. 35 C. 40 D. 45
A car travels in 2 hours. What is its average speed in ? A. B. C. D.
A company's profit is shared among three partners in the ratio . If the largest share is , what is the total profit? A. B. C. D.
An item costs before VAT. If VAT is , what is the total cost of the item? A. B. C. D.
Explanation: This topic focuses on powers (indices), their inverse operations (logarithms), and irrational numbers involving roots (surds). It requires understanding and applying the laws of indices and logarithms to simplify expressions and solve equations. Standard form (scientific notation) is also covered. For surds, the key skills are simplification, rationalization of denominators, and performing basic arithmetic operations.
Questions:
Simplify . A. B. C. D.
Solve for in . A. 2 B. 3 C. 4 D. 5
Express in standard form. A. B. C. D.
Simplify . A. B. C. 5 D. 6
