Question

What is the sum of the numbers which belong to one figure only?

• A. 5
• B. 16
• C. 21
• D. 24

Hint:

In figure puzzles, always carefully track overlaps. Only count those elements that are completely enclosed in just one shape.

Answer 1

The Correct Option is C

We are asked to find the sum of numbers that belong to exactly one figure only. Let's identify the numbers that appear in only one figure (i.e., not in overlapping regions): Number 1 appears only in the circle.
Number 2 appears only in the square.
Number 3 appears only in the square.
Number 4 appears only in the hexagon.
Number 5 appears only in the circle.
Number 7 appears only in the triangle.
Now summing these values: \[ 1 + 2 + 3 + 4 + 5 + 6 = 21 \]
