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.
In the figure, DE//BC: DB//FE: DE = 2cm, FC = 3cm, AE = 4cm. Determine the length of EC.
4cm
6cm
3cm
2cm
1cm
Correct answer is B
Angles ADE and EFC are similar,
Therefore,
= \(\frac{x}{3} = \frac{4}{2}\)
= \(\frac{x}{3} = 2\)
x = 3 x 2 = 6
387
493
502
441
634
Correct answer is C
Possible multiples of 8 and 9 = 72, 144, 216, 288, 360, 432, 576, 648.
\(\frac{387}{8}\) has remainder = 3; \(\frac{387}{9}\) has remainder 0.
\(\frac{493}{8}\) has remainder 5; \(\frac{493}{9}\) has remainder 7.
\(\frac{502}{8}\) has remainder 6; \(\frac{502}{9}\) has remainder 7.
\(\frac{441}{8}\) has remainder 1; \(\frac{441}{9}\) has remainder 0.
\(\frac{634}{8}\) has remainder 2; \(\frac{634}{9}\) has remainder 4.
Hence 502 is the answer.

Correct answer is C
a = 2i - 3j - 3i + 6j
= -i + 3j
= \(\sqrt{5 \times 2}\)
= \(\sqrt{10}\)
3 + \(\sqrt{3}\)
5 + \(\sqrt{3}\)
