Preparing for JAMB Mathematics 2026? This guide provides 10 carefully selected questions based on common exam patterns. Each question includes options, the correct answer, and a short explanation to strengthen your revision.
Question 1: Percentage Loss
Mr. Abora bought a car for ₦200,000 and sold it for ₦170,000. What is the percentage loss?
A. 10%
B. 12.5%
C. 15%
D. 18%
Answer: C. 15%
Explanation:
Loss = ₦200,000 − ₦170,000 = ₦30,000.
Percentage Loss = (30,000 ÷ 200,000) × 100 = 15%.
Question 2: Arithmetic Progression
Find the 19th term of an A.P. where the first term is 5/6 and the second term is 8/6.
A. 20
B. 9
C. 9.5
D. 10
Answer: C. 9.5
Explanation:
Common difference = (8/6 − 5/6) = 0.5.
Tₙ = a + (n−1)d = 5/6 + 18×0.5 = 9.5.
Question 3: Simple Interest
Calculate the simple interest on ₦10,000 for 3 years at 8% per annum.
A. ₦2,400
B. ₦3,000
C. ₦2,800
D. ₦2,000
Answer: A. ₦2,400
Explanation:
I = PRT/100 = 10,000×8×3 /100 = ₦2,400.
Question 4: Ratio
Divide ₦3,000 between A and B in the ratio 2:3.
A. ₦1,200 and ₦1,800
B. ₦1,500 and ₦1,500
C. ₦1,000 and ₦2,000
D. ₦1,800 and ₦1,200
Answer: A. ₦1,200 and ₦1,800
Explanation:
Total ratio = 2 + 3 = 5.
A gets (2/5×3,000)=₦1,200, B gets ₦1,800.
