2cm
20cm
200cm
2000cm
Correct answer is B
1 litre = 1000cm3
1800 litre = 1800 x 1000cm3
l x b x h = capacity
600 x 150 x h = 1800000
h = \(\frac{1800000}{600 \times 150}\)cm
h = 20cm
If 85% of x is N3230, what is the value of x?
N2745.50
N3714.50
N3800.00
N4845.00
Correct answer is C
85% of x = 3230
\(\frac{85}{100} \times x\) = N3230
x = \(\frac{100}{85}\) x N3230
x = N3800.00
If 92x = \(\frac{1}{3}\)(27x), find x
2
1
-1
-2
Correct answer is C
92x = \(\frac{1}{3}\)(27x)
(22)2x = \(\frac{(3^{3x})}{3}\)
(34x) = 33x - 1
4x = 3x - 1
4x - 3x = -1
x = -1
Express 2.7864 x 10-3 to 2 significant figures
0.28
0.27
0.0028
0.0027
Correct answer is C
2.7864 x 10-3 = 0.0027864
= 0.0028(approx. 2 s.f)
What is the median of the following scores: 22 35 41 63 74 82
82
52
49
22
Correct answer is B
22 35 41 63 74 82
Median = \(\frac{41 + 63}{2} = \frac{104}{2}\)
= 52
