What number is missing to complete this mathematical reasoning challenge?

Many people say they are bad at mathematics, however, this area of ​​knowledge is present in everything in our routine. Furthermore, one of the best ways to encourage improvement in mathematics is to challenge yourself to answer questions that involve this discipline. That's why today we bring you this math reasoning challenge to test your skills!

understand the challenge

In this challenge, we find some simple mathematical operations, which are addition and multiplication. However, the items we are adding or multiplying are not numbers, but illustrations!

Thus, the first step will be to identify which number corresponds to each image, that is, how much they are worth in the equation. This will be possible through the analysis of the results of each line, where we can deduce the value of each figure.

For example, on the first line we have three figures of a pair of sneakers that, added together, result in the number 30. When considering that the pairs have the same value, just divide the final result by the number of items, that is 30/3 which is equal to 10. Now, you will have to do similar operations on the other lines to find the answers.

What is the solution to the challenge?

The beginning of this challenge can be quite simple, but in fact it becomes more complex as more items are added. After all, in the second row there are no longer just pairs of sneakers, as there is also the figure of a man who is repeated twice, while in the third row the figures of whistles appear.

Again it will be necessary to find the values ​​referring to these two images, and we will use the results for the comparison. Furthermore, we already have the value of a pair of sneakers, which is 10, so that only remains to identify the numbers of the other two figures. To summarize the results, we schematize everything in operations, check it out:

• Shoes: 10;
• Male: 5;
• Whistles: 4;
• only 1 whistle (according to the 4th line): 2
• Man without the whistle (according to the 4th line): 5 – 2 = 3
• First Row: 10+10+10=30;
• Second Row: 10+5+5=20;
• Third Row: 5+4+4=13;
• Fourth Row: 10+(3×2)=16.
