A house bought for N100,000 was later auctioned for N80,000. Find the loss percent.
20%
30%
40%
50%
60%
Correct answer is A
Loss = N(100,000 - 80,000)
= N20,000.
Loss percentage = \(\frac{20,000}{100,000} \times 100%\)
= 20%

2 - 2log32
3 - log32
4 - log32
Correct answer is B
2log\(_{3}\) 6 + log\(_{3}\) 12 - log\(_{3}\) 16
= \(\log_3 6^2 + \log_3 12 - \log_3 16\)
= \(\log_{3} (\frac{36 \times 12}{16})\)
= \(\log_{3} (27)\)
= \(\log_{3} 3^3\)
= \(3 \log_{3} 3\)
= 3
Simplify: 16\(^{\frac{5}{4}}\) x 2\(^{-3}\) x 3\(^0\)

Correct answer is C
16\(^{\frac{5}{4}}\) x 2\(^{-3}\) x 3\(^0\)
= \((2^4)^{\frac{5}{4}} \times 2^{-3} \times 1\)
= \(2^5 \times 2^{-3} \times 1\)
= \(2^2\)
Express \( \frac{8.75}{0.025} \) in standard form
3.5 x 10-3
3.5 x 10-2
3.5 x 101
3.5 x 102
3.5 x 103
Correct answer is D
\(\frac{8.75}{0.025}\)
= \(\frac{8750}{25}\)
= \(350\)
= \(3.5 \times 10^2\)
