1. (a) In a class of 30 girls, 17 play football, 12 play hockey and 4 play both games.
Draw a Venn diagram to illustrate the given information
Let
U = Total number in class
F = Number of girls who play football
H = Number of girls who play hockey
n = Number of girls who play none of the two games
How many girls play:
(α) one or two of the games;
= 13 + 4 + 8
= 25
(β) none of the two games?
= 30 – 25
= 5
(b)
Total area of shaded portion
= Area of semi-circle – Area of the triangle ABC
Area of semi-circle =
= ×22/7×14×14
= 11×2×14
=
Area of triangle ABC = b h
= ×|AC|× |OB|
= ×28×14
= 14×14
=

2. (a) Two consecutive odd numbers are such that seven times the smaller, subtracted from nine times the bigger, gives 144. Find the two numbers.
(b) A paint manufacturing company has a machine which fills 24 tins with paint in 5 minutes.
(i) How many tins will the machine fill in
(α) 1 minute, correct to the nearest whole number?
(β) 1 hour?
(ii) How many hours will it take to fill 1440 tins?
(c) Given that ,a=3,d=4 and n=10, find the value of s.
a. Let the first (smaller) odd number = n
Then the next (bigger) odd number = n + 2
Seven times the smaller = 7n
Nine times the bigger = 9 (n + 2)
Hence ⇒ 9(n+2)-7n=144
⇒ 9n+18-7n=144
⇒ 9n-7n = 144-18
⇒ 2n = 126
⇒ n =
⇒ n = 63
Therefore the smaller odd number is 63
And the bigger odd number = 63 +2 = 65
(b) A paint manufacturing company has a machine which fills 24 tins with paint in 5 minutes.
(i) How many tins will the machine fill in
(α) 1 minute, correct to the nearest whole number?
If 5 minutes → 24 tins,
then 1 minute → =
tins ≈ 5 tins
Hence, 1 minute → 5 tins (to the nearest whole number)
(β) 1 hour?
If 1 minute →
then 1 hour (60 minutes) → ×60
= 24 × 12
= 288 tins
(ii) How many hours will it take to fill 1440 tins?
If 288 tins → 1 hour
then 1440 tins → ×1 hour
= 5 hours
(c) Given that s=n/2 [2a+(n-1)d],a=3,d=4 and n=10, find the value of s.
⇒ s=[2×3+(10-1)4],
⇒ s=5 [6+(9)4],
⇒ s=5 [6+36],
⇒ s = 5(42)
⇒ s = 210

(d) Measure
(i) |BY|;
= 4.8 cm [± 0.1 cm]
(ii) |YC|;
= 4.8 cm [± 0.1 cm]
(iii) the base angles of triangle BYC.
= 20.5° [or 20° or 21°]
(e) What type of triangle is BYC?
= Isosceles triangle
4. (a) The table below shows the ages of students admitted in a hospital.
Age (years) | 10 | 11 | 12 | 13 | 14 | 15 |
Number of Students | 5 | 1 | 7 | 10 | 3 | 4 |
Use the information to answer the following questions:
(i) What is the modal age?
(ii) Calculate, correct to two decimal places, the mean age of the students.
(b) Rice is sold at GHc 56.00 per bag of 50 kg. A trader bought some bags of rice and paid GHc 1,344.00.
(i) How many bags of rice did the trader buy?
(ii) If the trader retailed the bags of rice at GHc 1.40 per kg, how much profit was made on 1 kg of rice?
4. (a) The table below shows the ages of students admitted in a hospital.
Age (years) | 10 | 11 | 12 | 13 | 14 | 15 |
Number of Students | 5 | 1 | 7 | 10 | 3 | 4 |
Use the information to answer the following questions:
(i) What is the modal age?
= 13 years (the age with the highest no. of students)
(ii) Calculate, correct to two decimal places, the mean age of the students.
Mean age =
=
= \frac{ 377 }{30}
=
= 12.57 years.
(a) (ii) ALTERNATIVE APPROACH (using the table)
Mean age =
=
=
= 12.57 years
b.
(b) Rice is sold at GHc 56.00 per bag of 50 kg. A trader bought some bags of rice and paid GHc 1,344.00.
(i) How many bags of rice did the trader buy?
No. of bags bought =
= 24 bags
(ii) If the trader retailed the bags of rice at GHc 1.40 per kg, how much profit was made on 1 kg of rice?
Profit = Selling Price – Cost Price
Cost Price of 1 kg =
= GHc 1.12
Selling Price of 1 kg = GHc 1.40
Therefore Profit made on 1 kg = 1.40 – 1.12
= GHc 0.28
(b) (ii) ALTERNATIVE APPROACH (using the totals)
Total amount of rice = 24 × 50 kg
= 1200 kg
Total Retailed (selling) price = GHc 1.40 × 1200
= GHc 1680
Total cost price (given) = GHc 1344
Profit on total amount = Total SP – Total CP
= 1680 – 1344
= GHc 336
Profit on each kg (1 kg) =
= GHc 0.28
