The Mandurah region has 32 registered Uber cars and drivers. Of the 32 cars, ½ are Holdens, ¼ are Fords and the rest are Toyotas. How many cars are Toyotas? Explanation of answer: Step 1: To find out how many Toyotas there are, we must find out how many Holdens and Fords are being used for Uber. Step 2: Of the 32 cars, ½ are Holden. Divide 32 by 2 to get 16cars. This is the same as multiplying 32 by ½. Step 3: Of the 32 cars ¼ are Fords. Divide 32 by 4 to get 8 cars. This is the same as multiplying 32 by ¼. Alternatively you could divide 32 by 2 to get 16, and then divide 16 by 2 to get 8 cars. This is the same as multiplying 32 by ½ and then by ½ again (32 x ½ x ½ = 32 x ¼ = 32 ÷ 4 = 8). Step 4: If you have 32 cars total and 16 are Holdens and 8 are Fords we can subtract those totals from 32 to get the number of Toyotas. 32 – 16 = 16, 16 – 8 = 8. We have 8 cars that are Toyotas. Step 5: The correct answer is – b) 8 Alternative explanation: Step 1: A half is the same as two quarters. If half the cars are Holdens and one quarter are Fords, then in total, three quarters of all the Uber cars are not Toyotas. Step 2: Since “the rest are Toyotas”, that means that one quarter of all of the cars are Toyotas. Four quarters minus three quarters leaves one quarter. Step 3: All we have to work out is how many cars one quarter of 32 is. Divide 32 by 4 to get 8 cars. This is the same as multiplying 32 by ¼. Alternatively you could divide 32 by 2 to get 16, and then divide 16 by 2 to get 8 cars. This is the same as multiplying 32 by ½ and then by ½ again (32 x ½ x ½ = 32 x ¼ = 32 ÷ 4 = 8) Step 4: The correct answer is – b) 8 a) 6 Refer to Explanation of Answer b) 8 Correct Answer c) 12 Refer to Explanation of Answer d) 16 Refer to Explanation of Answer None Question 65. The birthdates of four friends are below: Who is the youngest? Explanation of answer: Step 1: As all the dates are presented in different format, we need to look at what common numbers are the same and then find the points of difference. Firstly, look at the year they were all born: 1975, this year is the same for all friends. We can’t determine who is the youngest from this info. Step 2: Next we should look at the months. These are different, two are in number form and two are in word form. If we place them in month order; 03 is March, then April, then May then 06, which is June. We can now find out who is the youngest from this info. Step 3: Anyone born in March, April or May would be older than someone born in June, so the person who is the youngest in this group of friends would be the one born in June. This is John. Step 4: The correct answer is – d) John a) Peter Refer to Explanation of Answer b) Bruce Refer to Explanation of Answer c) Phillip Refer to Explanation of Answer d) John Correct Answer None Question 66. This graph shows the average daily power usage of a family home over 2 years. Approximately, which season had the largest difference in power usage between the two years? Explanation of answer: Step 1: To answer this question you must compare the data from each season in 2014 to the same season in 2015 and find the approximate difference between the two. For example summer 2014 had 800 kWh usage and summer 2015 had about 780 kWh usage, which equals a 20 kW difference. We need to do that for each season to find the answer. Step 2: Autumn 2014 = 550 kW, Autumn 2015 = 530 kW = Difference of 20 kW Step 3: Winter 2014 = 700 kW, Winter 2015 = 750 kW = Difference of 50 kW Step 4: Spring 2014 = 600 kW, Spring 2015 = 580 kW = Difference of 20 kW Step 5: The season with the largest difference in power usage is Winter Step 6: The correct answer is – c) Winter a) Summer Refer to Explanation of Answer b) Autumn Refer to Explanation of Answer c) Winter Correct Answer d) Spring Refer to Explanation of Answer None Question 67 a.At the end of the trading day a newsagency has a number of notes in the till. They are:a) What was the amount collected in notes?Explanation of answerStep 1: To find out the answer for a) you must find out the totals of all the notes. 2 x \$100 = \$200, 3 x \$50 = \$150, 1 x \$20 = \$20, 4 x \$10 = \$40, 5 x \$5 = \$25.Step 2: Then add them together: \$200 + \$150 + \$20 + \$40 + \$25 = \$435. Step 3: The correct answer is c) $435 Please select your answer $385 $400 $435 $460 Question 67 b.At the end of the trading day a newsagency has a number of notes in the till. They are:b) \$43.75 was collected in coins; in total how much was collected altogether (notes + coins)?Explanation of answer:Step 1: To find out the answer you must find out the totals of all the notes. 2 x \$100 = \$200, 3 x \$50 = \$150, 1 x \$20 = \$20, 4 x \$10 = \$40, 5 x \$5 = \$25.Step 2: Then add them together: \$200 + \$150 + \$20 + \$40 + \$25 = \$435. Step 3: Now that you know the amount for notes, you can add the coins to the notes to get the answer. This is: \$435 + \$43.75 = \$478.75. Step 4: The correct answer is d) $478.75 Please select your answer a) $475.75 b) $476.75 c) $477.75 d) $478.75 Question 68. Mark filled up 5 buckets of water and weighed each one. He wrote the weight on each bucket. If he goes to pick up the two heaviest buckets how many kilograms would he be holding in total? Explanation of answer: Step 1: To answer this question you must know decimal places and the place value of each number. The closer the number to the decimal place (on the right hand of the decimal place) the larger the value of the number. For example 0.2 is ten times larger than 0.02. We have to look for the two largest values to add together. Step 2: The find the two heaviest buckets, we must find the two buckets that add to the largest value. For example: 8.2 kg + 8.032 kg = 16.232 kg, which is answer d) Step 3: 8.2 kg + 8.302 kg = 16.502kg, which is answer c) Step 4: 8.2 kg + 8.32 kg = 16.520 kg, which is answer b) Step 5: 8.302 kg + 8.32 kg = 16.622kg, which is answer a) Step 6: The correct answer is – a) 16.622 kg Alternative explanation: Step 1: Arranging the four different weights top to bottom from largest to smallest we get: 8.320 – largest 8.302 8.200 8.032 8.020 – smallest Step 2: We are only interested in the two largest weights, 8.32kg and 8.302kg. Adding these together gives us 8.32 kg + 8.302 kg = 16.622kg, which is answer a). Step 3: The correct answer is – a) 16.622 kg a) 16.622 kg Correct Answer b) 16.520 kg Refer to Explanation of Answer c) 16.502 kg Refer to Explanation of Answer d) 16.232 kg Refer to Explanation of Answer None Question 69. You have 4 Masters Choc milk containers. Each has 600 mL of Choc milk in them. You are sharing the Choc milk with 5 friends. You have five 450 mL glasses to share the milk with. How much milk would you have left over after filling those 5 glasses? Explanation of answer: Step 1: Figure out how much Choc milk we have first. Four containers with 600 mL each means 4 x 600 mL = 2,400 mL Step 2: Figure out how much milk needs to be shared. Five glasses that hold 450 mL each means 5 x 450 mL. Let’s break down that sum. 5 x 400 mL = 2,000 mL, 5 x 50 mL = 250 mL. 2,000 mL + 250 mL = 2,250 mL. Step 3: Find the difference between 2,400 mL and 2,250 mL = 2,400 mL – 2,250 mL = 150 mL Step 4: We have 150 mL of the Choc milk left over. Step 5: The correct answer is – c) 150 mL a) 50 mL Refer to Explanation of Answer b) 100 mL Refer to Explanation of Answer c) 150 mL Correct Answer d) 200 mL Refer to Explanation of Answer None You’ve already answered some of the questions!
