N676.50
N820
N1,640
N4,920
Correct answer is C
I = N123; R = 3%' T = 2\(\frac{1}{2}\) yrs; P = \(\frac{100 \times 1}{RT}\)
P = \(\frac{100 \times 123}{3 \times 2.5}\)
principal(P) = N1640

Correct answer is D
Excellent = 360° - (120° + 90° + 80°)
= 70°
Number of excellent students = \(\frac{70}{360} \times 36\)
= 7 students
Find the area of the trapezium above.
91 cm2
78 cm2
60 cm2
19 cm2
Correct answer is C
Area of trapezium = \(\frac{1}{2} (a + b) \times h\)
= \(\frac{1}{2} (7 + 13) \times 6\)
= \(60 cm^{2}\)
In the diagram above, PQR is a circle centre O. If < QPR is x°, find < QRP.
x°
