The value of each shape is a positive, single digit. What is the value of the triangle ?
A 4 B 6 C 8 D 9 E 10
B
Bearing in mind that the numbers involved can be only positive single digit numbers, 15 factorises as 3 X 5. The yellow parallelogram is then either 3 or 5. If it is 5, then on dividing 5 into the value of the red triangle to get a value of 2 means that the triangle is of value 10, not a single digit number. Hence the yellow parallelogram has value 3, which means that the red triangle must be of value 6, answer B in order to give an answer of 2 when divided by 3. To complete the array and provided a check on the working, the green pentagon has a value of 2 so that 6 – 2 = 4 and 2 + 5 = 7.
