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.
\(\frac{YX}{ZX}\)
\(\frac{YX}{YZ}\)
\(\frac{ZX}{YZ}\)
\(\frac{YZ}{XY}\)
Correct answer is D
The two triangles are similar
\(\frac{FG}{YZ}\) = \(\frac{FH}{XY}\) = \(\frac{GH}{YZ}\) = \(\frac{FG}{FH}\) = \(\frac{YZ}{XZ}\)
36o
60o
70o
72o
75o
Correct answer is D
\(\frac{26}{130}\) = \(\frac{x}{360}\)
130x = 26 x 360
= 9360
x = \(\frac{9360}{130}\)
= 72o
2.5
56.0
56.2
56.3
6.5
Correct answer is B
Total score for 2A & 2B = 4200
mean score = \(\frac{4200}{40 + 35}\)
= \(\frac{4200}{75}\)
= 56
6\(\frac{1}{3}\)
20
21
176\(\frac{4}{9}\)
None of the above
Correct answer is C
y = \(\frac{4x}{9}\) + 1, z = \(\frac{4y}{9}\) + 1, z = \(\frac{4}{9}\)(\(\frac{4}{9}\) x + 1) + 1
= [\(\frac{4}{9}\)(\(\frac{4}{9}\)(99) + 1]
= \(\frac{4}{9}\)(45) + 1
= 21
\(\frac{2}{n + 1}\)
(-1)n + 1 \(\frac{2}{n + 1}\)
(-1)n \(\frac{2}{n + 1}\)
\(\frac{n}{2n - 1}\)
(-1)n\(\frac{n}{2n - 1}\)
Correct answer is C
(-1, \(\frac{2}{3}\), -\(\frac{1}{2}\), \(\frac{2}{5}\)......)
nthterm is (-1)n\(\frac{2}{n + 1}\)
Since (-1)n will always be negative for n = odd
