Ladi sold a car for N84,000 at a loss of 4%. How much did ladi buy the car?
80,500
80,640
87,360
87,500
Correct answer is C
p>The car was sold at 96% ---- N84,000.00
The price of the car is 100% ---- ?
\(\frac{4}{100} \times \frac{84,000}{1}\);
= 3360
Car's price = 3360 + 84000
= 87360
\(2\frac{1}{2}\)

10
80
Correct answer is D
\(y \propto \frac{1}{x^2} \Rightarrow y = \frac{k}{x^2} \Rightarrow k = yx^2\\
k = 1\frac{1}{4} \times 4^2 \Rightarrow k=\frac{5}{4}\times \frac{16}{1}=20\\
∴y = 20 \div \left(\frac{1}{2}\right)^2=20\times \frac{4}{1}=80\)

288
Correct answer is B
Volume of rectangular packet = (16 x 12 x 6)cm3 = 1152cm3. Volume of cube of sugar = 2 x 2 x 2 = 8cm
∴ The number of cubes f sugar \(=\frac{1152}{8}=144\)

9.8ϖcm2
Correct answer is C
Area of a sector \(=\frac{\theta}{360}\times \pi r^2\\
\left(\frac{144}{360}\times \pi \times \frac{3.5}{1} \times 3.5\right)cm^2 = 4.9\pi cm^2\)
\(15\sqrt{3}m\)
\(15\sqrt{2}m\)
\(10\sqrt{3}m\)
\(5\sqrt{3}m\)
Correct answer is A
Tan 60º = \(\frac{15}{x}\)
cross multiply:
x = \(\frac{15}{\sqrt3}\) = 5\(\sqrt3\)m
