Each symbol has a numerical value. The total for the symbols is written at the end of each row and column.
Can you find the missing total that should go where the question mark has been put?
? = 21
â«Ž = 8
â–³ = 6
⬡ = 7
â—¯ = 4
Using the bottom two rows, we interpreted that there are three circles in both rows, meaning that the remaining shapes are a triangle and square. We then realised that the sum of the borrom row was 20 and the one above that was 18. So, we found the difference between the results, which was 2 meaning that the circle minus the square was two. Or the square minus the triangle was 2. Then, we used the values to figure out that the square was larger than the triangle as the square had 20 and the triangle was 18. So we figured out that the square minus the triangle was 2.
We then made an educated guess about what the traingle and the squares values was incorporating the equation:
â«Ž - â–³ = 2
So we tried and figured out the value of the square was 8 and the value of the triangle was six.
For the row that was equivalent to 18, the triangle was 6 and you had three circles which altogether was equivalent to 12. So one had to equal to 4 as there were three circles.
We then had to figure out what the value of the hexagon was. So, we saw two coloumns that contained a hexagon. Then, we used the column that was equivalent to 23. Since we knew what the square and the circle were equivalent to, we added the terms and found the difference from to total.
â«Ž + â—¯ + â—¯
= 8 + 4+ 4
= 16
Total - 16 = x
Total = 23
23 - 16 = x
x = 7
Therefore,
⬡ = 7
