Question 1
LEVEL 4
In a sale, normal prices are reduced by 20\%
In the sale the price of a dress is \pounds220
Calculate the normal price of the dress.
Select the correct answer from the list below:
A: \pounds264
B: \pounds250
C: \pounds275
D: \pounds300
CORRECT ANSWER: C: \pounds275
WORKED SOLUTION:
We know prices are reduced by 20 \%, so the prices in the sale are 100 \% - 20 \% = 80 \% of their original value.
80 \% = 0.8.
Divide the sale price of the dress by this decimal equivalent, to get the original value:
\pounds220\div0.8=\pounds275
Question 2
LEVEL 4
In a recent maths exam, Frazer scored 70\%
He answered 42 marks correctly.
Work out the total number of questions in the test.
Select the correct answer from the list below:
A: 60 marks
B: 50 marks
C: 55 marks
D: 70 marks
CORRECT ANSWER: A: 60 marks
WORKED SOLUTION:
70 \% = 0.7.
Divide the number of marks Frazer scored, by this decimal equivalent, to get the number of questions in the test:
42 \div 0.7 = 60 marks
Question 3
LEVEL 4
In a sale, normal prices are reduced by 42\%
The price of a CD tower is \pounds31.90
Calculate the normal price of the CD tower.
Select the correct answer from the list below:
A: \pounds50
B: \pounds55
C: \pounds48
D: \pounds52
CORRECT ANSWER: B: \pounds55
WORKED SOLUTION:
We know prices are reduced by 42 \%, so the prices in the sale are 100 \% - 42 \% = 58 \% of their original value.
58 \% = 0.58.
Divide the sale price of the CD tower by this decimal equivalent, to get the original value:
\pounds31.90\div0.58=\pounds55
Question 4
LEVEL 4
Each year the price for of a season rail ticket increases by 3\%
The price in 2019 is \pounds556.20.
Calculate the season ticket price in 2018.
Select the correct answer from the list below:
A: \pounds550
B: \pounds547
C: \pounds565
D: \pounds540
CORRECT ANSWER: D: \pounds540
WORKED SOLUTION:
We know prices are increased by 3 \%, so the prices after the increase are 100 \% + 3 \% = 103\% of their original value.
103 \% = 1.03.
Divide the 2019 price of the season ticekt by this decimal equivalent, to get the original value:
\pounds556.20\div1.03=\pounds540
Question 5
LEVEL 4
A car garage is having a 20\%sale off the normal price.
Tommy pays £5200 cash for a car.
Calculate the normal price of the car.
Select the correct answer from the list below:
A: \pounds6255
B: \pounds5800
C: \pounds6500
D: \pounds6000
CORRECT ANSWER:
WORKED SOLUTION: C: \pounds6500
We know prices are reduced by 20 \%, so the prices in the sale are 100 \% - 20 \% = 80 \% of their original value.
80 \% = 0.8.
Divide the sale price of the car by this decimal equivalent, to get the original value:
\pounds5200\div0.8=\pounds6500
