If the pass mark was 4. What percentage of the pupils failed the test?
20.0%
37%
62.5%
80.0%
Correct answer is A
No. of pupils that failed = 1 + 3 + 4 + 8
% failed = \(\frac{8}{40} \times 100\)% = 20.0%
How many pupils took the test?
36
38
39
40
Correct answer is D
No. of pupils = 1 + 3 + 4 + 7 + 8 + 6 + 6 + 4 + 1 = 40

Correct answer is B
area of larger circle = 100\(\pi\)
\(\pi r^2 = 100\pi\)
R2 = 100
R = 10(Radius)
Area of smaller circle = \(49 \pi\)
\(\pi r^2 = 49\pi\)
r2 = 49
r = 7(radius)
Since R = x + r
x = R - r
x = 10 - 7 = 3
60o
70o
120o
160o
Correct answer is C
Q1 = 50(alternate angle)
Q2 = 180o - 110o (straight line angle)
Q2 = 70
PQR = Q1 + Q2
= 50o + 70o
= 120o
