And the third and final problem involves another picture.
The picture features different pieces of fruit and sums and asks people to work out how many pieces of fruit are left.
The first sum shows that three apples equals 60.
The next one shows that cherries plus two bananas equals 20.
An apple plus two bananas equals 38.
So what is the sum of an apple plus cherries plus a banana?
You have to work backwards through each sum to reveal the numeric value of each fruit.
Here’s a look at the answers to the questions.
2. There are 12 triangles.
3. The answer is 31.
The value of the apples is 20 (60 divided by three), bananas are nine (18 divided by two) and cherries are two.
