- A78
- B93
- C94
- D108
Explanation
In the given Venn diagram, letting the regions be counted, the condition that the number of elements in A is twice the number in B fixes the unknown region X at 93. This matches the worked solution published with the diagram and an independent solved key. Hence X is 93.
