Identify these questions

Now that we’re more familiar with worded questions, we're going to extend our knowledge further of coding and solving worded problems to apply to questions where they want you to find an unknown with 1 variable.

These questions look like this:

One box has 4.7 kilograms of chocolates. Another box has 2.5 kilograms of chocolates. How much weight must be removed from the first box and placed in the second so that they are both of equal weight.

A 0.9 kilograms

B 1.1 kilograms

C 2.2 kilograms

D 3.6 kilograms

You can identify these questions as they’ll ask to you find the value of an item. There will be words like “how much…” which are giveaways when identifying this type of question.

The strategy to answer these questions

To answer these questions the process that you follow is the same as previous checkpoints, however, there's 1 more addition being:

• Illustrate the concept/images if you're unsure

The learning is heavily dependent on the practice questions so watch the video carefully as we go through example questions.

Example Question/s

Watch video for explanation of the following question/s:

A bag of clothes weighs 9 kilograms and another weighs 21 kilograms. How much weight must be removed from the second case and placed in the first so that they are both of equal weight.

A 5 kilograms
B 6 kilograms
C 7 kilograms
D 15 kilograms

Kyle runs 100 meters South, then 200 meters East, then 300 meters North, then 300 meters West, then 200 meters South and then 100 meters West.

How far from the start is he?

A 100 meters
B 200 meters
C 400 meters

If it is known that every 2 grams of sodium generates 40 calories, and 3 grams of sugar generates 60 calories, to ensure that lowest number of calories, a person should consume:

A A fruit bar with 400 base calories and 6 grams of sugar
B 200 calories of oatmeal with 4.5 grams of sugar
C 15 grams of sugar
D 300 calorie steak with 6 grams of salt
E A 400 calorie soft drink

Key Rules to remember:

• Illustrate the concept.
• Notate key elements.
• Evaluate and choose your correct answer.

Practice time!

Now, it's your turn to practice.

Click on the button below and start your practice questions. We recommend doing untimed mode first, and then, when you're ready, do timed mode.

Every question has two solutions videos after you complete the question. The first is a quick 60 second video that shows you how our expert answers the question quickly. The second video is a more in-depth 5-steps or less explainer video that shows you the steps to take to answer the question. It's really important that you review the second video because that's where you'll learn additional tips and tricks.

Once you're done with the practice questions, move on to the next checkpoint.

Now, let’s get started on your practice questions.
