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.
(2.6, 2.6)
(2.5, 2.6)
(2.6, 2.5)
(2.5, 2.1)
Correct answer is B
Arrange the numbers in order, 1.6, 2.1, 2.1| 2.4, 2.6| 2.6, 2.6, 3.7
n = median = \(\frac{2.4 + 2.6}{2}\)
= 2.5
m = mode = 2.6
∴ (n, m) = (2.5, 2.6)
35 years
40 years
42 years
54 years
Correct answer is C
Total age of the whole family = 21 x 14 = 294
Total age without the grandfather = 21 x 12 = 252
Age of grandfather = 294 - 252
= 42 years
30o
60o
112.5o
157.5o
Correct answer is D
Rice = 75g, Margarine = 40g, Meat = 105g, Bread = 20g, Total = 240
Angle of sector represented by meat
= \(\frac{105}{240}\) x \(\frac{360°}{1}\) = 157.5°
2\(\sqrt{5}\)
3
4
4\(\sqrt{3}\)
Correct answer is D
xz2 = 62 + 62
36 + 36 = 72
xz = \(\sqrt{72}\)
6\(\sqrt{2}\) = xT
\(\frac{6\sqrt{2}}{2}\) = \(\frac{3}{\sqrt{2}}\)
OT2 = 52 + (3\(\sqrt{2}\))2 = 25 + 18
OT = 4\(\sqrt{3}\)
440\(\pi\)cm3
1100\(\pi\)cm3
4400\(\pi\)cm3
1100\(\pi\)cm3
Correct answer is A
Volume of cylinder pip (V) = \(\pi\)h(R\(^2\) - r\(^2\))
= 100\(\pi\)(7.2\(^2\) - 2.8\(^2\))
= 100\(\pi\)(51.84 - 7.84)
= 100\(\pi\) x 44
= 440\(\pi\)cm\(^3\)
