Show answer & explanation
Correct answer: B
In the Venn diagram, we need the region that is common to all three sets: Brown, Car and Trouser. The number 10 is placed inside the Brown region, inside the Car oval and inside the Trouser region. The nearby number 4 is inside Car and Trouser but outside Brown, so it is not counted. Therefore, the number of items that are Brown, Car and Trouser all three is 10.
