How good are you with figures and formulas? Find out with these Mathematics past questions and answers. This Test is useful for both job aptitude test candidates and students preparing for JAMB, WAEC, NECO or Post UTME.
N36,000
N44,000
N40,000
N15,000
Correct answer is C
Total of their ages: 18 + 20 + 22 = 60
The second staff will get \(\frac{20}{60} \times 120,000\)
= N40,000.00K
(x − 5) 2
(x + 5)(x + 4)
(x – 5)(x + 3)
(x + 3) 2
Correct answer is B
\( x^2 + 9x + 20 \)
Find the two numbers whose product is 20 and its sum is 9}
\( 5x \times 4x = 20x^2\)
\(5x + 4x = 9x\)
\((x^2 + 5x) + (4x + 20)\)
\(
x(x + 5)+ 4(x + 5)
= (x + 5)(x + 4)\)
1 \( \frac{3}{8}\)
2 \( \frac{3}{4}\)
4 \( \frac{3}{8}\)
3 \( \frac{1}{5}\)
Correct answer is C
1¼ ÷ [ 2 ÷ ¼] of 28
Apply BODMAS rules
\( \frac{5}{4}\) ÷ [ 2 ÷ ¼ × 28 ]
\( \frac{5}{4} ÷ \frac{2}{7} \)
\( \frac{5}{4} × \frac{7}{2} \)
\( \frac{35}{8}\)
= \(4 \frac{3}{8}\)
In a town of 6250 inhabitants, there were 62 births during 1984. Find the percentage birth rate
3%
1.0%
2.5%
5.40%
Correct answer is B
Percentage birthrate = \(\frac{62}{6250} \times 100%\)
= \(\frac{6200}{6250}\)
= 0.992% \(\approx\) 1.0%.
43o
47o
54o
86o
Correct answer is A
Construction: draw a line from Q to point P and another line from S to point P.
< SOQ = 2< QPS (< at centre is twice < on the circumference)
< QPS \(\frac{86}{2} = 43\)
< SQR = < QPS ( < between a chord and tangent = < in the alternate segment)
< SQR = 43o
