**IQ test solutions**

Before you look at the IQ test solutions, have you tried to solve all the tasks yourself? If you haven't completed all the puzzles, that's not a bad thing. It is important that you test yourself first before you jump to the solutions.

The answers will help you better understand or help you if you have not come to the result on your own. And, of course, they serve as a check whether the results found are correct:

**Task 1: What number is continues?**

To recognize the logic behind the number sequence, you need a little mathematical skill and an understanding of how the following number comes about. The following applies in this series:

A number is multiplied by itself, and the next calculation step is - 18. This results in 5 - 25 - 7 -49 - 31. So the next step is to multiply by yourself: The number you are looking for is 31 times 31 = 961.

**Task 2: How do you weigh?**

You initially weigh only 6 balls, 3 each per weighing pan. Out

there are 3 possible results that will bring you closer to the solution:

1. The left bowl is heavier, so here is the heavier ball.

2. The left shell is lighter; therefore, the heavier ball must be in the right bowl.

3. Both bowls are of equal weight: the heavy ball is under the remaining 3 balls.

You put the weighed balls aside and distribute 2 of the remaining 3 balls in a weighing pan. Again there are 3 options, and one of them clarifies the question of which ball is the heaviest:

1. The left bowl is heavier, so you have the lighter ball in the right.

2. The left bowl is lighter, so you have the heavier ball in the right bowl.

3. Both bowls are of equal weight: the heaviest ball is the one that remains.

**Task 3: who is it?**

Such questions about family trees are classic logic tasks and can be included in IQ tests - but they are regularly confused. It helps to clarify the solution as clearly as possible and to break the sentence down into its parts. Start at the end: ... is my father's son.

Since there are no siblings, this person is the man himself. The father of the person depicted is thus the father of the man looking at the picture. The picture shows the viewer's son (or daughter).

**Task 4: How much does it cost?**

An inconspicuous task that is often done wrong. Many instinctively say: the apple costs 1 dollar the yogurt 10 cents. However, this cannot be because the apple costs 1 dollar more - in the premature solution, the difference is only 90 cents. The apple, therefore, has to cost 1.05 dollar, and the yogurt only 5 cents.

**Task 5: Who is the youngest?**

A classic task in the logic test can only be solved by logical thinking and reasoning. To put the age in order, the connections must be examined carefully: Sascha is as old as Iris. Since Sascha is older than Lilli, Iris of the same age is automatically older than Lilli. Nid is older than Iris (and therefore also Sascha).

The solution is, therefore: Lilli is the youngest in the group. Sascha and Iris are the same age in the middle, and Nid is older than everyone else.

**Task 6: How long does it take?**

No, the solution is not 13 days. If the weed doubles every day, it covers half of the field one day before the whole field is overgrown. So the answer is: it takes 25 days.

**Task 7: What is true?**

Here you get to your goal by concentrating only on the statements that are given. Answer C is correct. If all birds have wings and all wings are made of feathers, then all birds also have feathers.

**Task 8: How old am I?**

This can be solved with a relatively simple mathematical equation. Take the information out of the puzzle and paste it into one.

Equation, where X is the age you are looking for: X 15 = 4 * (X-3)

Then dissolve the whole thing after X, and it comes out: X = 9, so the girl is 9 years old, in 15 years it is 24, and that is 4 times as old as it was 3 years ago (when she was 6 years old).

**Task 9: Which switch fits which lamp?**

You have to think not only logically, but also around the corner: First press the left switch and wait a minute or two before switching it off again. Next, turn the middle switch to on and immediately go into the room with the lamps. The light bulb that is now lit logically belongs to the middle switch. You can also assign the other 2 pears by feeling the temperature. The warm lamp belongs to the first switch, the cold one to the third, unused switch.

**Task 10: How much do you have to drink?**

If 99 percent of 200 bottles are red wine, this makes a total of 198 bottles of red wine and just 2 bottles of white wine. To reduce the percentage to 98 percent, 100 bottles of red wine have to be drunk - then there are 98 more red wines and the 2 untouched bottles of white wine. 98 of the 100 bottles that were left then gave the required 98 percent.

**Task 11: Which day is it?**

The solution is Sunday. The day before yesterday was the day after Tuesday - so Wednesday. That means Friday is today. So it's Sunday in 2 days.

**Task 12: What is the rule?**

If you only calculate, you won't get anywhere here. Rather, it is an alphabetical arrangement from A to Z: eight, three, one, five, nine, six, seven, four, and two.

**Task 13: What does the number series look like?**

A little mathematical skill is required to come up with the solution: 4 - 6 - 10 - 18 - 34 - 66 - 130. To get to the individual digits, you have to start at the given "4" and calculate back from there :

4 is 1 greater than 3, which should be half of the following number, so the second digit is 6. If you reduce it again by one, you get the

5 as half of the following number, the third digit is, therefore, a 10 ... With this calculation, you can quickly find all the numbers you are looking for.

**Task 14: How do the terms relate to each other?**

A lizard creeps - this is a typical form of transportation. Fluttering is the right answer for the butterfly, and it is also called wobbling.

**Task 15: Which term applies?**

The adjective ambivalent has many synonyms. Often it becomes ambiguous or ambiguously.

**Task 16: What was it about?**

In Task 2, you should use a scale to find out which of the 9 balls are the heaviest. For this, you were only allowed to weigh twice.

**Task 17: Which word does not fit?**

Whether a pond, North Sea, river, ocean, swimming pool, lake, or stream - in all cases, these are areas in which water is usually contained. However, the swimming pool is artificially created.

**Task 18: Which term is an antonym?**

Gallophobia (or Francophobia) is the aversion to everything that is French or concerns the culture and customs of France. The opposite would be gallophilia or francophilia.

**Task 19: How do you form the correct analogy? **

The tree relates to the forest like the brook to the river.

**Task 20: Which number must follow?**

The answer is 4. The numbers 324, 108, 36, and 12 were each replaced by 3 divided, thus 12: 3 = 4.
