Correct answer is C
Number that score less than 5: 5 + 6 + 4 + 3 + 2 = 20
Total number of students: 5 + 6 + 4 + 3 + 2 + 4 + 6 + 5 + 1 + 3 + 1 = 40.
%age of students that failed: \(\frac{20}{40} \times 100% = 50%\)
12
9

7
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 = \(\frac{1}{2} (a + b) \times h\)
= \(\frac{1}{2} (7 + 13) \times 6\)
= \(60 cm^{2}\)
