If four 1 kg bags of mixed cereal grains cost $96, how much would seven and a half 1 kg bags cost? Explanation of answer:Step 1: We need to figure out what one 1 kg bag costs. We have to divide 96 by 4 to find our answer. We could round up the \$96 to \$100 and divide by 4, which would give us \$25 or 4 lots of \$25. As we have rounded up by 4, we should subtract \$1 from each group of \$25. This means that the 1 kg bag would cost \$24. Alternatively we can split up the \$96 into \$80 and \$16 and divide each by 4 (80 ÷ 4 = 20, 16 ÷ 4 = 4). This gives us 20 + 4 = \$24.Step 2: Now that we know that each 1 kg bag is \$24 we have to multiply that 7.5. It would be easier to split these numbers again to 7 and 0.5. 7 x 24 (7 x 20 = 140 and 7 x 4 = 28, so 7 x 24 = 140 + 28 = 168). 0.5 x 24 (½ x 24) = 12. 168 + 12 = 180. The 7.5 1 kg bags of mixed cereal would cost \$180.Step 3: The correct answer is – d) $180 a) $164 Refer to Explanation of Answer b) $168 Refer to Explanation of Answer c) $175 Refer to Explanation of Answer d) $180 Correct Answer None Question 122.Harry was going to a National Basketball League game. He had to travel on the train to and from the game plus purchase tickets for the game. The game tickets cost \$64. The return train ride cost \$15.How much did his trip out to watch the game cost him?Explanation of answer:Step 1: Simply add the two values together. \$64 plus \$15 = \$79. Note that a “return” trip is a two-way trip, so we don’t double the \$15 train fee to cover each leg of the journey.Step 2: The correct answer is – b) $79. a) $83 Refer to Explanation of Answer b) $79 Correct Answer c) $75 Refer to Explanation of Answer d) $68 Refer to Explanation of Answer None Question 123.Sandy went to the Sydney Opera House to watch a performance. She was sitting in the Box B area. She was sitting in seat 34.Which statement is true? Explanation of answer:Step 1: She is not sitting directly in front of the platform, so statement a) is incorrect.Step 2: Box D is not directly next to (adjacent) Box B, so statement b) is incorrect.Step 3: She is not near Door 14, she is near Door 5 or Door 6, so statement c) is incorrect.Step 4: When reading the seat numbers in Box B, there are 68 seats available. Seat 34 is the middle number between 1 and 68. So she is sitting right in the middle of Box B. Statement c) is correct.Step 5: The correct answers is – c) She is sitting right in the middle of the Box B area. a) Sandy is sitting directly in front of the platform Refer to Explanation of Answer b) Box D is directly adjacent to where Sandy is sitting Refer to Explanation of Answer c) She is sitting right in the middle of the Box B area Refer to Explanation of Answer d) She is near Door 14 Refer to Explanation of Answer None Question 124.Mandy used this ice tray to make ice cubes for her water cooler.She had to fill the ice tray 7 times to get the amount of ice blocks required for the cooler.How many ice blocks did she make?Explanation of answer:Step 1: Look at the ice tray and count the amount of holes.Step 2: The answer is 8 holes.Step 3: The questions says Mandy filled it 7 times.Step 4: This means you need to multiply 8 times 7 to get the total number of ice cubes.Step 5: The correct answer is – a) 56 ice cubes. a) 56 Correct Answer b) 52 Refer to Explanation of Answer c) 48 Refer to Explanation of Answer d) 44 Refer to Explanation of Answer None Question 125.Dana is a baker. She is making hot cross buns at her store for Easter. She packages them into boxes of 6. She made 220 hot cross buns.How many hot cross buns were left over?Explanation of answer:Step 1: To find out how many hot cross buns were left over we need to divide 220 by 6. To find an easier way to do this lets bunch the boxes of 6 into groups of 10. This means that there are 60 hot cross buns per bundle of ten packets. We know that in one bundle there are 60 hot cross buns, in two bundles 120, in three bundles 180, in 4 bundles 240 hot cross buns. Since we only have 220, we don’t have 4 bundles of 10. It must be 3 bundles (180 hot cross buns) plus some extra packets.Step 2: So we have 3 bundles of hot cross buns giving us 180 hot cross buns. We can now use the 6 times tables to figure out how many packets there are left. If we multiply 6 x 6 we get 36 hot cross buns. If we add 180 plus 36 we get 216 hot cross buns. We are 4 short of 220 hot cross buns.Step 3: This means that there are 36 packets of 6 hot cross buns, with 4 hot cross buns left over.Step 4: The correct answer is – c) 4 a) 8 Refer to Explanation of Answer b) 6 Refer to Explanation of Answer c) 4 Correct Answer d) 3 Refer to Explanation of Answer None Question 126.The Hawaii Ironman event is considered one of the most gruelling and challenging Ironman events in the world. The record for the fastest time completing the event was set in 2011 at 8 hours 3 minutes and 56 seconds.If the world record for finishing the race is at 3:03:56 pm, what is starting time of the race?Explanation of answer:Step 1: If the race finished at 3:03:56 pm and we know that it took 8 hours, 3 minutes and 56 seconds to complete then we need to subtract that total from the finishing time.Step 2: 3 pm minus 8 hours = 7 am (3 hours to noon, then 5 hours to 7 am). Our time now is 07:03:56. We then can subtract 3 minutes and 56 seconds from the total to give us 7:00 am (07:03:56 – 00:03:56 = 07:00:00).Step 3: The correct answer is – a) 7:00 am a) 7:00 am Correct Answer b) 7:13 am Refer to Explanation of Answer c) 7:15 am Refer to Explanation of Answer d) 7:30 am Refer to Explanation of Answer None Question 127.A small cafe in the city decided to keep a tally of the amount of coffees customers bought each week.How many customers purchased more than 6 coffees in the week?Explanation of answer:Step 1: The question asks how many customers purchased more than 6 coffees in a week. This means that we need to count the three numbers in the three rows that tell us how many customers bought 7 to 15 coffees in the week.Step 2: We need add 8 + 5 + 2 to get the amount of customers buying more than 6 coffees. This equals 15 customers that bought more than 6 coffees in the week.Step 3: The correct answer is – c) 15. a) 10 Refer to Explanation of Answer b) 12 Refer to Explanation of Answer c) 15 Correct Answer d) 18 Refer to Explanation of Answer None Question 128.A plumber turns a tap handle through 5 full revolutions to turn it off.How many degrees did he turn the tap handle through?Explanation of answer:Step 1: The question states that the bulb was rotated through 5 full revolutions. One revolution is 360 degrees so we need to multiply 360 by 5 to get our answer.Step 2: Let’s break down the number 360 into two parts; 300 and 60. Let’s multiply 300 by 5 = 1500. Let’s multiply 60 by 5 = 300. Add 1,500 and 300 together to give = 1,800.Step 3: The plumber had to turn the tap handle through 1,800 degrees to turn the tap off.Step 4: The correct answer is – a) 1,800 degrees. a) 1,800 degrees Correct Answer b) 1,650 degrees Refer to Explanation of Answer c) 1,500 degrees Refer to Explanation of Answer d) 1,350 degrees Refer to Explanation of Answer None Question 129.Anna bought 11 packets of 6 bread rolls for \$3.20 each. She paid with a \$50 note.How much change should she receive?Explanation of answer:Step 1: To find this answer we should multiply \$3.20 by 11. However, if we multiply \$3.20 by 10 and then add \$3.20 to the total we will get the same answer. 10 x \$3.20 = \$32.00 + \$3.20 = \$35.20.Step 2: We now need to find the change from a \$50 note. \$50 – \$35.20 (\$50 – \$35 = \$15, and \$15.00 – \$0.20 = \$14.80) = \$14.80.Step 3: Anna received \$14.80 change from the \$50 note.Step 4: The correct answer is – b) $14.80 a) $13.40 Refer to Explanation of Answer b) $14.80 Correct Answer c) $15.20 Refer to Explanation of Answer d) $16.30 Refer to Explanation of Answer None Question 130.John was building a play house for his children. He measured the top section for some beams that he needed for the roof. As he was building one of the other sections he realised that the original measurement for the roof was incorrect. He needed an additional 15% of wood for the beam.The original measurement for the beam was 1,800 mm. What does the new length of the beam need to be?Explanation of answer:Step 1: We know that the original beam was 1,800 mm and that we need an additional 15% of that beam to make part of the roof. So we need to find 15% of 1,800 and then add it to 1,800.Step 2: 10% of 1,800 would be 180. To find 10% we can remove one 0 from 1,800 to get the total of 180. As 5% is half of 10% we can halve the 180 to find 5%. 180 ÷ 2 = 90. Now to get 15% we add the 180 (10%) and 90 (5%) together to give 270.Step 3: We now have the extra 15% which equals 270 mm. Now add 270 mm to 1,800 mm to give the new length of beam required. 1,800 mm + 270 mm = 2,070 mm.Step 4: The correct answer is – b) 2,070 mm. a) 2,050 mm Refer to Explanation of Answer b) 2,070 mm Correct Answer c) 2,095 mm Refer to Explanation of Answer d) 2,115 mm Refer to Explanation of Answer None Time's up Submit a CommentYour email address will not be published.
