Venn diagrams Numerical Reasoning Question
Of 88 people, 53 like tea, 43 like coffee, 14 like both. How many like neither?
A35
B45
C6
D14
E82
Worked solution
At least one = A + B − both (subtract the overlap once); neither = total − that. The correct answer is 6. Traps to avoid: 35 comes from the "removed one set" error; 45 comes from the "removed one set" error; 14 comes from the "gave overlap" error; 82 comes from the "gave at least one" error.
